I do not know why we spend so much time here "learning" about old doubles when we could just ask a seller, like this one, for the facts and gems of wisdom he knows.

All my Lefevers, Foxes, Parkers, Smiths and even Ithacas have that shiney chrome lining. Do yours? Or is it worn out so that you can not see it anymore? New selling feature, %chrome left in double gun bores. Should be real easy to see and rate just behind %blue or case color left on the gun for a value determination.
