NOTE: I’m still looking for more Arnolt pieces, heaters, bulkhead plates, bypass tubes, rheostat switches, valves head plates etc. All parts considered


While in recuperation I’ve had time to restore 3 of the Arnolt heaters I have acquired. (4 in all thus far). There are 3 variations between them.

The first heater I will show is one I purchased from Doug Pelton at From The Frame Up several years ago off of eBay. Doug couldn’t provide any history regarding this odd duck.

This heater box is slightly smaller in size and has a more Art Deco design influence to it. The original paint was a smooth beige finish. The fascia is cast. The doors are on top and the core is at the bottom with air being drawn upwards to the doors. The doors also have rather ornate cream colored Bakelite knobs but at the moment they are packed away somewhere yet to be installed. It has two studs at the rear for a mounting bracket. This particular heater had a full width plate bolted to the studs with a 45° bend at the top. My initial plan was to use this bracket along with rubber hose covered exhaust pipe clamps and mount it directly to the scuttle hoop.

The Restoration:

After media blasting I used a Rustoleum Bronze hammer tone finish with a light fog of Rustoleum 2X Chestnut Brown. The color changes in depth and tint depending on the light source. The heater core was pressure checked, fins were straightened and several beads of silicone were laid on the tanks to act as anti vibration bumpers. The old rubber had long deteriorated. The motor was disassembled, cleaned, inspected, oiled and new cloth wiring installed. New rubber bump stops were added to the doors as well as a new grommet for the wiring to pass through

Next up is what I would probably say is the typical Arnolt Heater. A square enclosure with radius edges on five sides. The fascia is cast and it’s profile curved inward at the bottom. The core is on top with air being drawn downward to the doors.

The Restoration:
I have two of this style. The process was the same as previously described with the exception of paint experimentation.

The first picture shows the same finishing technique as described previously.

The third picture was painted only in Rustoleum 2X Chestnut for a smooth appearance. It’s a little darker than the original finish but I don’t think it’ll be a big detractor when tucked up under the dash.

The last heater I have yet to do is similar to the second post. It is a square box with radiused edges and corners. The big difference is the box is entirely tin including the fascia. It has the feeling of being a cheap bargain basement knockoff even though it has the identifying features of an Arnolt. The core and doors are typically oriented and the mounting is the typical Triangulated T bracket that suspends the heater off the back of the battery tray. A curiosity with this heater is that the core is honeycombed rather than flat finned

I have purchased some lighted 12v rheostat switches off of eBay along with some 5/8” x3/8NPT brass water shut off valves similar to this well used one

I chose this particular style of switch because all my TDs happen to have red interiors and the fascia will complement the upholstery.

The heater bypass is an original Arnolt piece. I have bought copper tubing to fabricate the plumbing but may go down to my local tubing specialist and see about buying some steel tubing instead to make an accurate reproduction of the original.

There has been a vender on eBay manufacturing aluminum head plates for a heater access point. I have messaged him regarding making these with 3/8NPT to directly accept these water valves. He won’t be making anymore until spring. Unfortunately he is raising his price as the auction wasn’t allowing for any profit margin. I plan to order 2-3 of these for my own use.

Should I manage to come across a few more heaters at a price where I can afford to rebuild them and be able to make a little in return I may entertain offering complete kits with the necessary pre formed hoses, clamps, tubing, valves and switches to aide others in an easy installation process. If not then I will shelve them for future projects down the road

Cheers

Good to hear you are staying busy...you need to build your strength back up so you can push the TD out here to have breakfast with us this spring grinning smiley


Where did you find the valves? I'd like to put one on my TF to completely block off the water flow in the summer.

No worries car running GOFWest at Lake Tahoe in Sept. you should try and get up here for it. The WNMC Sacramento clubhouse is always open

Look up vintage heater shut off valve on eBay. Watch the sizes. 5/8 x 3/8NPT and 3/4 x 1/2NPT in the style I show. Also Z valves for in-line use.

Bill - I don't think that you've stopped since you got out of the hospital. Glad that you are doing well. The heaters looks good.

My Arnolt Heater has the cream color bakelite knob on the front only. The body is like your "typical Arnolt Heater." Hinge pins can be changed so that the door opens at the top or the bottom.

Do you know of the border and letters on the original Arnolt badge were raised? The reproduction is flat. I wonder if the decal could be lightly attached to the heater, then cut out the background to leave only the border and letters. Next attach a second badge over the first and burnish it so that the letters and border would be slightly raised.

I couldn't find any heater info by Ben Cordsen on-line today. Don't know if he still sells the Arnolt brand decal or sells heaters and parts.

They are on ebay. Email: don.paradowski [at] yahoo [dot] com

Hi Lonnie

Thank you for your comments. While true that the doors can be inverted to swing either way I believe that it is appropriate that they swing out at the bottom. This facilitated keeping dust and debris out of the box though that is just an opinion. I may not have been quite clear regarding my statement though. What I meant to infer was the door locations between the “early” Arnolt vs the typical style are in quite different locations.

Regarding the decal type and placement. I have ordered two of Don Paradowski’s reproduction “decals” and expect them in a few days. I’m not aware what the originals looked liked or what material they were made of but I suspect originally they may have been an embossed foil of some sort. I simply don’t know never having seen one intact. When I purchased the “decals” from Don I had messaged him regarding what material they actually were made from as my paint finish may not be compatable with their application. (Texture of surface area). I did not get a response from him as to whether they were foil, vinyl or Decalcomania (wateslide)

Also the area for the decal in the pentagon of the early Arnolt is about 50% smaller than the typical offering we are used to seeing. I will scan and downsize the examples I have coming from Don and reprint them on vinyl or water slide as seems appropriate. I have made my own waterslides in the past for other restoration projects with very good results. I’m sure all three heater examples likely carried a different Model # as well though I have only seen the one decal as an example of what has been offered.

I have never talked to Ben Cordsen. Is he the gentleman in Arizona? I have no contact information for him but would like to talk with him to get his perspective.

I would also be very curious if anyone could share more light on this early example. It’s the only one I’ve ever seen like it. I would expect to see them in MMM, prewar and early postwar T-series, tourers and saloons. But then I’m only assuming that Arnolt was supplying these items during that time frame. I have not tried to do any research in this area of thought.

I bought my heater from Ben 12 years ago. He is in Fort Collins Colorado. If you google his name it will come up with his business , which is art design.

Can anyone ID the heater below that came in my TF? There are no brand identifiers on the unit. The fan appears to be reostat variable control.

I just picked up the same heater as Charles94 at a local AACA silent auction along with a radiomobile 4202 from the same seller. If they both came from the same car I did find info on the radio that it was made 1951 – 1954 4202 Long & Medium Wave for World excl. Europe

Beautiful acquisition! It still works the auto-radio?
I just found this link for you.

Matthew. Not wanting to hijack my own thread. But if you are interested in selling the Smiths radio please contact me via PM. I’m looking to return one into my dad’s TD/c restoration. I bought one several years ago but it is in very poor condition and it’s restoration is in doubt
