Okay, it doesn't look like I'm going to find a nice Numrich-style parts diagram. That's okay I guess but I sure wish there was one in "The Ross Rifle Story". There are bits and pieces in there, but nothing in complete form. Ian McCollum a.k.a. "Gun Jesus" wrote a review of this book in his "Forgotten Weapons" series several years ago and described it as "deeply flawed". I have to agree.
