I will post a picture in a minute
Looks like the base to a hooded dash light. Several of my old tractors have them to light the instruments.
Chris, I have the same year car, I also have that on my dash however I think its a bulb socket not a knob
It is a dash light. Bulb and hood missing
Ever watch this old jack lemon movies like the great race it the Push the button MAX
John,Doug,Hal got it.
Sweet! I'm going to search for the rest of the light assembly!
so is it suppose to shine on the amp gauge or is it a map light
either/both, you can turn the cover whatever way you want the light to shine.
I ordered one from Lang's today.
It will also be handy to see the pedals when driving at night. I dangled a small flashlight from it to navigate the controls tonight. My neighbors are all having great fun riding in my "Chitty-Chitty Bang-Bang" car.
I stick one of these up and behind the dash. Its magnetic so it sticks. Its a handy place so you always have a flash light available AND at night you can reach up and click it on leaving it stuck up behind the dash and it provides a nice interior night light for the lower cabin
