Technical Bendix 2 way vacuum switch

I salvaged this Bendix 2 way vacuum switch from a old Chevy 2 ton truck. It controls the shift for the 2 speed rear axle. It's cable operated with a knob on the dash. It has a number in the housing. 377265 any info on it would be useful. Years made, model number, applications. Thank you

 

My first thought is could it be used to operate a Columbia 2 speed diff. ?

 

Would you happen to still have this? Would you sell it?

 

Hello. Checking back! I’m interested!

 

When I was a kid, my dad had a ‘46 1.5 ton Chevy with a two speed rear, but it’s lever to shift was on the floor and seem to recall it was all manual, I/e a rod or cable maybe? to the rear. I recall him having to double clutch to go up or down.
Seems like vacuum would have been more modern than that?
The truck I drove for him a few years later was a 54 semi cab over 2.5 ton Ford, it had an electric shift 2 speed

Do you recall what the cab of the truck looked like?

 

Still interested if you still have to and want to sell it!

 

checking back to see if you still want to get rid of it!
