I'm not a collector but a shooter, however, I do like a nice looking gun.
One that has had a larger extension on the stock like the previous pic would not interest me, nor would a price for a well worn gun that was the same as a pristine one just because of the makers' name.
I can certainly deal with 2 1/2" chambers and tight chokes however, they are not an issue for me.

Of course I have shot all my vintage guns - what do you think they are called SHOT guns for??!!
