I have seen 25 round boxes made for export before WWII by both Remington and Winchester. Perhaps they were made by other US manufacturers but I have not seen them.
Below is a 9mm Browning Long 25 round box by Remington. I think it loaded in 1933.
I have seen a black & white drawing of a 9mm Luger 25 round box by Winchester, and I have been told that a Remington 25 round 9mm Luger box exists, probably much like the box above, but I have never seen it or a photo of it.
Does anyone have documentation on 25 round 9mm Luger boxes by US companies from before WWII?
Who all made these 25 round US export boxes and in what calibers???
