These particular rifles from Chas. A Heyer and co. are very hard to find any information on, I own a rifle almost identical to yours, except did not get as lucky on original condition, mine is drilled and tapped, and has been bored to 9.3x338, but otherwise is identical, they are a fine piece of history. I have looked long and hard to find the maker of these rifles, if they came from mauser, or were farmed out to a custom gunmaker, but have really found nothing. Any information that you have on this would be greatly appreciated. Thanks, Derek
