If it looks too good to be true......
The point is, there is quite the market for upscale forgeries of both old Remington and old Colt revolvers. In this instance, the wealth of inspector's marks makes me extra suspicious, as if the primo condition wasn't suspicious enough.
Some of these forgers turn out beautiful work these days that only an expert (and maybe not even then) can tell from the real deal. Always check the provenance of these purported old revolvers..... as there should be some documentation or verifiable history accompanying them as to where exactly they came from. They don't just magically appear
For reference re; 'inspector's marks' & lettering, read:
http://www.restoration-gunsmith.com/ltrng.htmlAnd I believe that authentic old Civil War issue Colts and Remingtons in 80%+ new condition fetch upwards of $30,000 or more, so if the price wasn't near that then that's the first clue usually that something is amiss.
Another example of a ripe fake market is 'old' American Indian tomahawks. Virtually 99.9% of purportedly old tomahawks sold on eBay are fakes, and the ones that aren't (and even some that are) are so expensive that it takes an expert to know the difference.
