Cab 13 door knob

[Bruce Parker (RIP)]

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.

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

Thank you Phil, the basic knob shape looks very common, the tang receptacle on the back seems less common than a round hole. The round holed wersion exists for choke and throttle cables (presumably threaded inside??) and for window cranks (pressed on to a rivet with circumferential ridges). I've checked some Chev parts suppliers and McMaster Carr online without finding the "right" knobs. I haven't checked my parts books to find out if the knobs have Chev or Ford numbers (and if they are CMP unique or generic parts), nor have I checked the Master Parts catalogs to see if they have other known applications. The research results will follow.

Hi Grant

FORD Knob - C29Q-812086

Chev group number 16.245 and 16.130 T-40854

I've been through my Chevy Mapleleaf master parts book but have not found the cross-over to the non military. When I need one I thought seriously about using the correct shape and milling out the slot on the back.

I'm surprised that in 30 years I have not lost one though.

Cheers Phil

A comparison of Chev door and choke/throttle knobs. Ford were different in that the door knobs were 'ringed' and quite reddish.

The knob that was on my door looks similar in external shape (but I have no idea if the inside or dimensions match) to a knob I found at www.obschevy.com listed as part number CET53V00 described as "47-50 Side vent knob", the colour for this is given as Maroon which is close to the parts of the knob I found that aren't cracked, faded and abraded.
