So Joe Poyer identified them in his book, interesting. You know I don't have any of his books other than his sniper books.

It's funny to me because he nails some stuff that is so spot on, that no one else in any book gets right. Then some other stuff he just is just so out there I have no clue where he got it.

But I didn't think too many knew about the off center apertures. That is neat.
