Thank you all for your kind remarks... I've always been a whole lot luckier than smart.

Of course, the sling well cut-outs shown above.

And here are some more...

There's a sticker on the bottom of the butt-plate Dunno what it might signify. I'd be glad to hear any ideas.

Then the marks in front of the trigger flat.

And then the bevel above the recoil lug. Maybe there was something there, maybe not??
