That rust wouldn't bother me at all ProHunter, so long as it's limited to the pan/frizzen area seen in the picture (i.e. the bore is clean). It appears to be fine surface rust. Just remove the frizzen and clean everything up with very fine (600 grit) emory paper. You want to polish the pan anyway, and 600 grit emory paper will do that well, or polishing compound on a felt polishing wheel in a Dremel tool. Get that rust off of the frizzen hinge and put some oil in that area. If there's rust in the screw channel, pulling a piece of cotton twine coated with polishing compound back and fourth through the hole should take care of it. (Bye the way, real men shoot flinters,
and caplocks,
and .22's,
and Daisy BB guns, sling shots, spit balls through plastic straws, etc., etc.)
