[R-390] R-391 Receiver

[DW Holtman]

Today I received a R-391 that I bought off Ebay, 7618164408. . It is 
very dirty and will require a complete tear down of the gears and 
motors. I'm in the process of down loading a manual off Bama. I have 
gone through 2 R-390A gear trains with no major troubles, how much 
harder is this going to be?

Any help and suggestions will be greatly appreciated.

Best,
