Thanks to all, esp. James Whisker, for the information regarding the attribution here and on the ALR page that has the images themselves.
It was brought to my attention that there are images of two other Fainot rifles in Heckert and Vaughn's Pennsylvania-Kentucky Rifle--and there are close resemblances between the patchbox on one of these rifles and the attributed Fainot pictured here. I assume those two Fainots are signed, since the Heckert/Vaughn book doesn't indicate otherwise and it's pretty responsible about noting what is unsigned and what signed.
I would assume (again, I'm new to all this) that, without at least one signed rifle by a given maker, it would be impossible to attribute any rifles to him? Or am I misunderstanding something about how expert attributions can be made? (That is, I assume that attributions are made by checking unsigned rifles against a known signed one.) I realize that attributions to a particular school or region could be made--but to a particular maker, I would think, would require at least one signed rifle by that maker?
Thanks again,
Scott
