Cab 13 door knob

[Grant Bowker]

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.
