The gun has been refinished. As noted earlier, the latch posts are blued---should be in the white (as should the entirety of the muzzle----muzzle and rib----which has yet to be shown)----never mind any other typical refinish clues which may be present. The trigger guard also appears to be blued---should be case hardened.

The Russian style trigger guard was definitely an option. I own the (Duffy) gun (noted above) pictured in N&J (page 190), and it letters right down the line----including the trigger guard (the spur of which is checkered).
