Just picked this GHE up from the FFL and looking it over had a few questions about some of the stampings on the water table and barrel flats.
1. I'm wanting to find out what the JG in a circle means (probably an inspector initials)
2. What's the 47 on the top right mean?
3. Next there is a 3 over a D.
4. Also, there is a K.
I know what the other markings are, 3 8 unstruck barrel weight, 12 ga. #1 frame
