what is he doing ? i have some with the wear marks and some with out . my oldest ( to me ) i got new 25 years ago it has wear marks , its been to the bottom of several beaver ponds while still in my hand ( buddy said he looked and all was left was my hat floating ) , it has been shot 1000's of times ( stock cracked in a dove field ) . The action is so loose /smooth you can pull the triger while holding gun muzzle up anf it opens all the way point it down and it closes . When hunting over the years it has been shot and had the action worked in some odd positions so the side stress could have caused the rub. IDK . some of the others were used and some show wear others don't . All seem to function as they should .
BTW , GEORGE FOSTER was my great grandfathers name .
