Well.... Browsing a few local friends for a 1911 frame and this is what I found.
The first, (more worn) gun is the one on gunbroker. The second, (not for sale currently), has been fired, maybe twice

. It looks completely untouched apart form a couple of tiny marks on the frame rail and the mark on the back of the frame from the toggle. Straw is 98% ? Both bores truly excellent.
The gun for sale has a little overall 'age' to it.
Both are so far beyond my ability to evaluate it's unreal.
But ifthey turn out to be genuine, at least I got to play with both !!
The carbine he has for sale made me drool, but same comments apply.
He seems to be a genuine guy I've dealt with before, certainly a pleasant chap. He would very much like to authenticate or disprove the originality of these pieces as he's a middle man in the deal.
Got to lie down for a minute; more money than my cars worth....
