I have an excellent Model 17. I purchased it in 1969. It has checkered forearm, and also solid matted barrel rib. Excellent condition. It is too light of shotgun to shoot clay targets with, but a joy for upland. Has a modified choke which throws Mod Imp patterns.
I have no idea of the value of such guns, mine has the 1915 John Browning Patent date stamped on the barrel. I have never seen one in as good of condition as mine. Pick up one if you get a chance!
I have one that used to belong to my grandfather. I think he got a lot of deer with it (slugs) according to my dad. I had it out a few weeks ago to try out some hand loaded buckshot. I like the smooth strong ejector. I don't have a very good photo of it but I will get one soon.
The buck loads did as good as I need, low recoil for the wife and daughter but kept almost all the lead on target at 25 yards. should take care of anything that would give them trouble around here.
