On the cover of Journal 480 is a picture of a Remington cartridge board owned by Fred Butt. The rounds all appear to be British military contract rounds from the 1940-41 period and include a 20mm Hispano headstamped to Bridgeport Brass Company (BBC).
Did Remington/DuPont own BBC or was there a commercial relationship between them? If not, why would the round be on the board?
All help appreciated,
