You are correct johngross, that is the one I'm referring to. It just concerns me that there is absolutely no documentation/pictures in any of the 'experts' books that make note of this strange deviation.
I am apprehensive about spending that much on something that may just be a very old copy.
If this was my pistol (and it is not) I would not worry so much about the wood as it is one piece. Unless you have a good set of hollow ground tip gunsmith screwdrivers and some penetrating oil, I would be leery of trying to remove the backstrap screws for fear of ruining the screwheads after who knows how many years since they were last removed.... one more thing on this old squareback -- the grips feel firm, but on one side near the bottom there is a small area where if I tap on the walnut grip with my finger nail you get a hollow sound (like if tapping on an empty eggshell). Everywhere else is a very hard and solid sound.
If I pull the (3) screws to remove the backstrap I'm assuming the grips will come off with the backstrap. I have never pulled this off any of my old Navys, but I have seen the walnut grips in a one piece configuration. Will they easily slip off the backstrap? I don't want to go messing about with something that I know nothing about.
With this strange sound when tapping I'm assuming that the grip in this area has been 'whittled' away on the interior surface for some strange reason or earlier repair. Under magnification there are some lines in the old grain pattern that might be where the grip had been repaired.
I just don't want to wreck anything during disassembly. I'm sure that the interior side of this grip would need some backing walnut epoxied to it for stabilization.
