Thanks for the responses so far guys. Good point about the top rib and guard screw. Also, Drew's 1910 pictured gun has more engraving on the side of the barrels. May be just a model year change but who knows. Here is a picture of the lower barrels. I have a couple more I will post as soon as I can, unfortunately they are not the best. When I took them I just found it to be an interesting gun and was not interested. But, after thinking about it the last few day I have become more interested. The gun does seem "to good to be true" so am looking for all the info I can get. Thanks
