something just says early MOPAR to me...but....with my vascular dementia, it could very likely be out of a Ford Taurus
I've driven cars with both of them in them at one time or another but can't remember what they were in. You get in ten or fifteen cars a day in a shop for a lot of years and you see a bit of everything. That ashtray matches the rest of the knobs on the dash though and I think all of the have that bezel around them.
Thanks for the website Stuart in MN. Looks like the speedometer is a Nash. Still not sure about the ashtray.
Ash tray looks like a packard 1950s. I think. Only round ashtray I have ever seen! Plugs right into the dash just right of the steering wheel.
