Where these the original components or were they added later on in an armory?

In the case of this .50 I think it's original fitting but later refinishing...but would need to examine it closely to be better informed.

M-1928A1

Nice early features on that one, paddle selectors, Waldemar Broberg marked instead of George Goll, Auto Ord marked...finned barrel and earlier Cutts, there were four patterns of Cutts compensators. Also BNP marked as it may have come out of UK in the early days when that stuff was around.

I had a '28...and converted it to an A1 config for shooting. Here's pics of it in '28 configuration.
