Beautiful brand new unused Clarostat 1 Meg linear taper NOS vintage pot from 1966. Specifically date coded 6652, so 52nd week of 1966. 

I have multiples of these for sale so if you decide to order pairs or more for your project, the date codes will match for guitar builds or what have you!

They are also stamped with another number CM 35548 and I an not sure what that pertains to, might be a Clarostat part number or a marking for some OEM, not sure. Shaft is 1/4" in diameter, smooth and the threaded collar reach is 1/4" in Long. They also include a full set of mounting hardware, lock washer, flat washer and hex nut. I measured the DC resistance of these parts with my Fluke ohm meter and they measure 1 Meg ohms at full travel. Tolerance for the most part is -0 up to +20 percent

Pretty cool to be able to reach back in time almost 60 years and buy some beautiful brand new quality parts like this, when they're gone they're gone!

Let me know if you have any other questions or need any other info or measurements.
