Miller, thanks for the correction. You are right of course. I was referring to the engraved scallop shell design of the push button. I've never seen that before on a Lefever, but this is by far the earliest one I've owned. My other two are 1898 and 1904 respectively. This gun does have a poorly done pistol grip, and I doubt it is the original trigger guard. I'll be converting it to a long tang straight grip, since originality has flown out the window with this gun.
Your 10ga sounds massive. Is it fun to shoot a 10lb gun? I don't think I've shot one more than 7.5lbs before. I've thought about getting a 10 at some point just for ducks and geese, but feeding them is the issue. Speaking of long chambers, my 1904 GE 12 (below, bottom pic ) has factory 2 7/8 chambers. Go figure.
