The "Line of Blue" on most RIA production is very narrow, unlike that of Springfield which is much wider. In most of them, it is less than 1/32 wide and in some probably not more than 1/64. I agree that on most of them, there is only a hint of a line. Apparently Rock Island did their final polish almost up to the guard. I should have made this distinction more clear in my book. Hopefully one of these days I will get my Bayonet Points article on the Model 1905 bayonet finished and will try to be more specific .

The one in the photo is about as wide as I have ever seen on a Rock Island.
