This isin't the same thing, but I was looking at a Colt Model M at a gun show that had a very attractive price and I noticed that the serial # had the wrong font. I brought to the dealer's attn. and he was quick to show me it matched the serial # under the slide. When I asked if the appropriate paperwork had been filed with the ATF due to changing the serial #, he became loud and belligerent telling me, " master gunsmith did that, there's nothing wrong with it!"

Needless to say, I walked away...

Duckboats, decoys and double barrels...
