Noice. ^_^ Mine's a post-War Bolo. c.1924. Also matching serial numbers, even the internals and grips -- except for the magazine base plate. Which isn't surprising. Of all the bits that coupld be lost, that's probably ##1.
My safety works the same way. You'll also notice that if you engage it with the hammer un-******, the safety pushes it back from the firing pin slightly. How far down have you stripped it? Field-stripped (Magazine baseplate, spring and follower removed; frame removed; action removed from receiver)? Or all the way down to individual components? I took mine apart when I first got it, action and everything, and let it all soak in WD-40 for a couple days. Wiped it all down while wearing inspection gloves and rebuilt it (some of those springs were
really fun :rolleyes ). It's just been lovely.
