That is a rather unique piece, but I don't know if I would think it is a highly desireable piece. I own a few cape guns, and they understandably are European. This gun has rather plain engraving and wood work. There is also something odd about the Damascus welds which are internal to the fore arm/action. It may be an optical issue, but it looks like the welds weren't completely struck or removed. The biggest negative would be the obviously terrible amateur resoldering of the rear of the rib.
I have several German cape guns with more and better engraving, platinum inlays, better wood and metal and better overall condition. I purchased several of these for less than $2000 delivered in the past year. One was a Sauer underlever from the same period that looked much better, materials and workmanship were to a higher standard, and it was chambered for a 16 gauge shotshell/20 gauge "bore rifle" combination. It was in like new condition and was well under $2000. I will have to say that some of this was due to the general confusion over the rifled barrel chambering.
Unless you found a buyer that was a Reilly fanatic or obsessed with owning a British Cape gun, I think the gun would be in that range.
