Beef,
That gun was definitely NOT "manufactured in the original old Colt Armory, under the blue dome." It was manufactured by Uberti in Italy.
As for the "Jesse Wales" inscription on the back strap, I would avoid it for that reason alone. Personalized inscriptions on firearms (or anything for that matter) tend to decrease resale value.
Sans the inscription, I would place the value of this gun, if in pristine condition, and at auction, in the $500 to $600 range at the extreme most - and only then because it is a very early example of the USFA line with a finish that was, back then, superior to that offered by Uberti and might, and I express "might," be of interest to a dedicated collector of USFA firearms.
I, for one, would not be interested.
