Anyone know if 1911 frame exclusively for that year or the same all the way to 1914? Any picture showing the difference be helpful. Thanks
Minor changes, almost every year (a hole or two here or there). How precise do you want to be?
The latter half of 1913 and '14 are basically the same as 1915, and are very different than the first half of 1913 or '12. Any frame from 1910 through '25 can work with some finagling. A 1911 frame has several major differences from a '14, mostly with the entire rear cross member. So it just depends upon what you want and how correct you want it to be?
