I was hoping someone might respond once you gave the dimensions.  The knife looks to me to have more of a "belly" than normal for a model 3 but that may just be the angle of the picture.  But to me what's really interesting is the rivet on the keeper strap.  I thought that ended in the late 40's.  Also seems unusual that it has a keeper rivet but no other rivets.  I think that's unusual. Well, except that with Randalls there seems to be an exception to every rule.  Nice knife.  Thanks for sharing.
