Side note to all of the above - one man's junk is another man's treasure. I frequently see old, worn out, should be thrown away firearms (mostly handguns) brought to the shop. Their owners ask about getting them put back into shooting condition only because the firearm was originally owned by their great-great-great-grandfather's fourth wife's cousin, twice removed. These owners are as anxious to get their prize back into working order as every other customer seeking repair service. Don't dismiss these older handguns as worthless, several of them could bring in respectable money to be used as parts donors.
