I recently got the top one. It is a 1956 vintage Ithaca 37 16 gauge.
The next picture is the newest one I am buying. A 1952 Ithaca. It will have screw in chokes put in, be reblued and have a correct recoil pad installed.
The last is my other Ithacas. Only the bottom gun has never harvested any game, mostly because it is 16 yrs old and still basically NIB. I restocked the laminate stocked one myself.
Each of these has its specific purpose and niche. For close quarters rabbits, the first 16 is a light, quick handling gun. The barrel is fixed choked modified.
I know where there is another one for sale.
