Some more pictures as promised:
Note the last picture which is a 1941-1947 Heater NOS they come with the discussed switch not rheostats. I have lots of NOS in box parts and Chevrolet sent the complete kits switches, brass ties, screws whatever until some one shows me different this is the standard dealer installed switch not rheostats. Accessory installation manuals also reference/show this switch not rheostats. A Chevrolet heater was a substantial option add on the price of a trucks (5-7% avg.) so it makes sense that they would be complete kits not parts of this and that, that is not the way the factory packaged kits are assembled. I have also added the original foot washer pump for comparison it is complete nothing else is needed to install.
