I am continually amazed by the lack of product knowledge exhibited by some gun dealers and FFL's, both in their online listings and in follow-up discussions with them. It's amazing that some of these guys can stay in business. I'm completing a long distance transaction now with a dealer who misrepresnted the chokes on a relatively well known NIB modern double because he didn't know how to read the markings on the box or on the barrels, doesn't have a choke gauge or a bore/choke mic, and doesn't have a set of calipers to tell me the OD at the muzzles so that I can determine whether screw chokes can be fitted. He owns the shop, but he doesn't know how to measure LOP. But, the gun is a good deal if it pans out, so I'm putting up with the lack of competence. His auction listing pictures were so bad that I needed a pic of the original box to verify the manufacturer and model.
