Good post!
A lot depends of course on the asking price, regarding evaluation.
If it is a top dollar price a buyer is wise to get it checked out by a pro to make certain that it is what it is claimed to be.
On the other hand if a guy is after a good shooter rather than a good collector rifle, and the price is right, some of the evaluation may be able to be relaxed a tad.
Doubles meant for very regular hunting use in all weathers can be forgiven for being a bit daggy and a bit worn so long as the daggs are mostly cosmetic rather than mechanical, and that the price reflects the condition.
There are some clunkers out there but there are also some good working guns, which may be a little rough around the edges but are still very capable of killing just as well for less money.
