First post, need help on a Winchester 5640289

[JimF4M1s (Deceased)]

Thanks Jim. I was aware of the various types of Underwood receivers purchased. I'm more interested in what if anything they did with other companies. For instance did they buy Rockola or NPM parts, or IBM stuff?

WB shows integrated parts from Inland, I.B.M., NPM, Saginaw Steering Gear, Std Prods, and Underwood. Stocks (1,500) from NPM. Most of the others were springs, pins, some slides, hammers, and extractors from others.
