The Sterlingworth cards are mostly pretty bleak, and imho for 90% of common Sterlingworths a letter isn't worth $30.
I guess just
some owners like to know the factory barrel length, factory choking, stock measurements, approximate weight as the gun left the factory......
and the factory shipping date and to who it was shipped in most cases.........which allows someone to buy and own an "unaltered" gun........
I agree that the Cody Firearms museum is a much more detailed informative source than the AH Fox Collectors.......I sometimes wish they had all the manufacturing records for U.S. sporting arms companies now long gone, not just for Winchester, Marlin, L.C. Smith and some others......most of their records are in original factory ledger form and more informative IMO..... they are super nice people to work with as well and always available for phone calls ......
Cody sends their factory letters out in a full size 9" X 10.5" envelope backed by cardboard which arrives unfoiled, not folded in a letter envelope with creases like the Fox people.......
Some folks don't care about records, details and alterations......some do......
