Yes, rechambered by Newton or under his direction by Adolph or some other gunsmith. I am not sure if Newton had a "shop" at that time. He located at 42-44 Niagara in Buffalo when he started to make his First Model 1916 and I am not sure what date he started at that location. That building is no longer standing altho he moved to the Jewett address in early 1917. That building is still being used by a fabricating firm and I was able to go thru it and take pictures of the area Newton used at that time.
