I like to do some of the smaller jobs on a project as I work on the big jobs. I am restoring the underdash defroster and heater control assembly for our '41 Pontiac. The paint is silver/gray hammered finish. The knobs are toast but all there. I need a 3D printer. I don't know what I'll do about the lettering on the front. I guess I'll save it as-is for now.
A modern sign shop should be able to recreate that lettering in the form of a decal that you could apply and then clear over top of to preserve it.
Here is one from ebay....runs around $9... 1939 1940 PONTIAC (ALL MODELS) HEATER CONTROL PANEL FACE DECAL STICKER NEW | eBay
vtx1800, great save on the knobs Papa in NC, what's the shaft look like that the knobs mount on? Is it the typically circular shaft with a flat? Could be plenty of knobs that will fit.
Yes those are the knobs! Three anyway, the one on the far right is a push/pull cable to operate the water valve under the hood.
The two on the left have a large hole that slips over a bulb socket, probably 3/8 or 7/16 in diameter. The third one fits over a splined shaft about 3/16 or 1/4 inch. Number 4 is a matching knob on a cable. Mine are pretty "crumbly" so I don't know if I can fix them with epoxy. I've thought about having my buddy turn some from wood, and leave the bulbs out of # 1&2.
