GM heater/defroster motor

Could some one help ID this motor? I found a NOS heater/defroster motor. It's 6 volt and GM part #5047733. The number is a bit high for my 50-52 Cadillac and in 53 Cadillac went to 12 volt. I suspect that it may be for a 53/54 Chevy or Pontiac, but not for my Cadillac. Any help would be appreciated. If you find the number you may have it for $10 + shipping. Ron

There's one on ebay right now with an asking price of $135. I like your deal. Wish I needed one.

There are 7 people watching the auction too.

The one that I have , as well as the one on ebay is not for the deluxe/automatic( 5047686) Cadillac system, but for the standard system. 1949-52 Chevys use the same motor, but Chevy used no ground wire. I presume that the motor is internally grounded and the screws complete the circuit GRD when mounted on the metal duct.??

sold it. Now to figure how to repair the original motor. Do they come apart to expose the armature/ windings?
