Is it me or do there seem to be a lot of classic air rifles coming on to the the market in "to good to be true" condition recently?

I've seen a couple of pre-war BSA's on the on-line markets recently which looked liked they had been completely re-blued and had the stocks stripped and varnished. This work looked to have been done to a very high standard, but none the less identifiable as a refurb.

All of these adverts made much of the seemingly mint condition of the gun, but there was no mention of refurbishment, and of course, top dollar prices were being asked.

Has else noticed this trend or am I just paranoid?
