The model 4 is a little plain Jane. Well, maybe it's a lot plain Jane. But I'm a sucker for a 16 gauge and I'd have paid more than $825 for it :-)

If it's a 1952 gun it's not likely to be a light game gun - most likely a medium game gun. Pics would be super in figuring out what it is (kyrieellis@aol.com). How much does the gun weigh, total?

On the chokes, that's M/F in the day of fiber wads and no shot cups to mention so it will probably shoot more like IM/XF. You might consider have it cut for choke tubes (Briley does a great job).

Congratulations on a nice gun.
