Scott guns of this period are beautifully designed, manufactured and finished and you will find them with all sorts of Gunmakers names on them.
My only concern with them is that, by definition, they are very early hammerless guns, look dated to some and so went out of fashion and as a result tended to get into the 'wrong' hands as in their shooting owners and the 'smiths that worked on them.
A good one in fine condition is a joy to shoot and own but one that has been used, abused and 'smithed by a blacksmith can be a horror.
One tiny tip, if the Crystal Ports are loose or have to be removed for cleaning, cut out some new gaskets for them using the thinnest glove leather you can find, feed well with hide food before fitting. It works a treat.
