Ok, at he risk of asking a dumb question, is there anywhere one can get an "Historical" letter on an older Ithaca gun as you can with a Parker, Fox and Winchester? I have looked but I cannot find such a service. I just purchased a copy of Walts "New Ithaca Gun Company, 2nd Edition" for research, but what is there beyond that? I'm looking at a nice Grade 3 ejector 20 gauge, and a letter would be very nice to have. Thanks.
