The estimates on the Westley and (especially) the A. Henry are way too high IMO.
The Westley "long range large game" rifles are much sought after but maybe not so much in an 1871 and with the exchange and premium, could nudge $10KUS which I just don't see on an "improved Martini".
Is the market up in the UK? Seems like the estimates for this kind of stuff are double what they were just a couple years ago.
