Not something I usually see at the same time. A pair of Cogswell & Harrison ‘Avant Tout’ (Translates to Above All) 12 Bore single trigger shotguns. These are a few numbers apart, one is 28″ and one 30″ and the latter has a very subtle and nicely fitted wooden extension to the butt but at first glance they could be stable mates.
Cogswell & Harrison single triggers have a bit of a reputation however I am not sure where from as they are normally OK to work on. My experience is, if there is an issue it will be down to previous work, such as the lower gun has had a screw glued in at some point. Such tricks are pointless and just bring the trade into poor repute and sadly they do show up and more often than I would hope for these days.
As ever, my poor picture does not do these guns justice. They are a pretty pair of guns and the wood is a good match, if it were not for numbers they would comfortably pass for a matched pair.
One thing I notice of such guns is they are usually reasonably straight in the stock and fit me well. I would happily be seen with either of these at a shoot and more importantly, I could hit things with them.
