Swing, I wasn't going to touch that one with a 10 foot pole. (God, don't I wish ! !)
Abberations scare me. I am comfortable with the norm. I believe in Sagan's theory of natural selection. I just wish it were a little faster.
Zund, I think you're petty much on top of it, however the underlying denial of what is tacit is, I believe, the issue here.
Lets say you found what you sincerely believed to be a mint 1866 Winchester and upon examination found it to be marked "Miroku" and "Uberti" and a few other less-than-desireable indicators of its value being other than what was first supposed.
Let's say further, that it shot as straight, or straighter, than an original 66, its general workmanship was acceptable, (it fooled you to start with, right ?) and it would likely last as long as an "authentic" rendition of what you supposed (and hoped) it was to begin with.
Now for the biggie question: How many can answer this truthfully ?
Would you still value the piece or would you relegate it to its proper niche and be on the lookout for other such "impostors"?
