... Look at the wood around the lockplate. Note the chips in the wood along the bottom edge and at the rear. A lock (not necessarily the one we see now) was at one time incompetently levered out. This is a common type of damage on guns that have been messed around.
BTW, I think that the dings between the backsight and the barrel band, referred to in a previous post, could have resulted from someone driving off the band with a screwdriver or something "pointy".
- More evidence of incompetent dismantling.
Finally, please note that - apart from the question of the manufacturing date, for which I do not possess the source information,***
- all my comments are based on LOOKING at what I can SEE in the photos. They do not depend on the type of gun.
LOOK at what you can SEE and ignore what the seller wants you to imagine!
***Oops! I must correct myself. Of course, it's in Frasca & Hill (which I have).
