Default Cab 13 door knob

A while ago it was mentioned in a thread that wasn't related to doors or knobs that it would be helpful if photos of the door knob used on Cab 13 doors could be posted so that people could look for suitable substitutes (or new replacements).

The pictured knob was on one of the doors that came with my C15A. The metal tang from the latch mechanism goes into the plain legs of the opening. The dimensions are: largest diameter 1", base diameter 5/8" (plus), height 7/8", height of dome above rim 1/8", rim thickness 1/8", opening for mechanism tang 1/8" x 7/16". I've no idea why the opening perpendicular to the tang is such a fancy shape unless the knob had a second aplication. The measurements were not taken to high precision. I haven't checked whether the same part number shows for Ford and Chev.

Does any one have ideas for a modern source, either identical or capable of modification? I would rather not cut down the latch mechanism to fit a round holed knob.

Grant..
If you could borrow one of those knobs to Jordan Baker ,he could manufacture them up by molding a new batch of knobs..The lad is a genius when it comes to little parts like that..
Could probably personalize a few for you with GB inset on the top..
but I imagine he could use a few too..
could get rid of lots of them..

Default How about......

.....making a mold of the vulcanized rubber used for casting lead soldiers..... and make them of pewter/lead....... melts at low temp..... and would not crack like plastic........once painted... you would not be able to ell them apart.

Let's turn the barn into a science lab....... Kaboom!!!!!

PS...... Back when I was in TO ..... I did cast some pewter buttons for my 1812 uniform..... so the learning curve would not be so steep !!!

..... would you like some grenades with that ...?

Default Original??

I've never seen a door knob like that one on a CMP before. There are the usual ones for Chev (brown, kind of squarish) and Ford (pinkish and 'ribbed'). Brian Asbury had some of the Chev ones and may still. The Ford ones were a little harder to find.

Your description of the Chev knobs sounds like the choke and throttle knobs listed for 1939 and 1940 Chevs (described as "rose tan" in some catalogs).
It sounds as if the press on knob to a rectangular tang was at least a semi-standard design since there now seem to have been at least three different moulds made to make them.
The design seems better suited for a sideways load than a pulling load, although it took a fair effort to take the knob off the tang. Any ideas what else they were used on? Think about knobs on almost anything. The tang seems too heavy duty for the old style toasters that had a flip down door on each side.

Default Some where I have seen a match

Some where in the past I remember coming across a knob like this in a catalog but have not been able to find it. I'm sure this was a standard shape for a knob.

I'll keep looking.

Cheers Phil

Hi guys

Thanks Alex for the kind words. Yes it would be very easy to cast these knobs in resin. The best would be to use a NOS one but it would be possible to clean that original one up.

Bob, I can get resin and dyes to make a hard durable "plastic" that would be in the same or close to colour of the orignal. Pewter would work but then you would always have the problem on paint chips and that they are metal and not plastic.
