Skeettx, I found that bit of Lowell history. I really question --
By 1922 the New-York-City-based National Lead Company, which also controlled the Winchester Repeating Arms Company,
Williamson stated that Winchester had been buying their shot from National Lead Co., but in 1911 when National Lead bought United States Cartridge Co., Winchester didn't want their shot supplier to be a direct competitor, so started planning their own shot tower which was completed in 1912 at a cost of $190,000.
In early 1926, National Lead Co. wanted to get out of the ammunition manufacturing business, pressure coming from the expiring lease on the factory buildings in Lowell. A deal was struck where Winchester acquired all the physical assets of USCC and 83 freight car loads of machinery were shipped to the Winchester plant in New Haven. USCC maintained their own sales and distribution networks selling their ammunition manufactured at Winchester's plant in New Haven.
