Oh come on, the gun on pg. 81 was made prior to WWII and has seen some field use and more than occasional oily rag swipe. Luvly vintage CC plus some patina of age and use if you ask me. That gun looked pretty darn close to Mikeys piece at the time it was made.
Yep, the piece on page 81 is factory original finish, but some nimrod carried it by the action as indicated by finish wear on the trigger plate and the barrels adjacent to standing breech.
