OK, for those of us that don't have the terminology down pat, how about a bit more help. The difference I see in the photos is that there isn't as much length in the receiver right behind the bolsters [ or fences ]. I had never heard of a flat-back sidelock before, or the term antlers used in gun terms. There use to be a place where all the terms were, but I couldn't find it. Thanks for any help. Paul
