The most glaring issue is the flip back sight. Not right, obviously. The waisted front sight looks correct, for the one photo he has. For 3K you'd think he'd have better pictures and more of them.
The price is of course out of line, or it would've sold. The stock I'm not sure about. These had a grooved front forestock. I'd think this one was re-stocked in 1939-1941 time frame.
