Thanks again for all of those who gave advice about my first sxs purchase. Today i brought home the gun. The price was right and the gauge is 16.
Can you guys tell me what I have. Year, etc.
I know it is a 16 with 70 chambers.

Marks are as follows (my digital camera just can't pick them up):
304
Choke 170
1kg191
u over (U with a * above).
lion over PV.
Crown over E over LG over * all in a circle.
horseshoe with 16-70 inside.

Thanks,
Stroud
