Heritage Guns' Comment

This superb gun was made in the very last years of the proprietorship of EF Paddison, nephew to the famous Thomas Boss, who took over the ownership of Boss & Co from his aunt, Emma Boss in 1872. Two years after this gun were made, John Robertson bought Boss & Co and developed it into probably the most exclusive London gunmaker name ever.
With its bar action locks, elegant sidelever and superb Sumner engraving, this gun represent the early departure from Paddison's very traditional preference for back actions and rotary underlevers. On taking over Boss & Co, Robertson changed the style of the guns to appeal to more modern tastes and these guns reflect many of the changes he introduced. Not surprisingly, he actioned and stocked this gun; the lockwork is by the famous lockmakers Stanton and the action bar is engraved with 'H&H HAM'S EJECTOR 16691'.
The gun was rebarrelled by the makers with steel chopperlump barrels in about 1927 and in the last few years it has been professionally restocked with beautiful walnut.
Reproofed to 2 ¾" nitro, it is a safe and beautifully balanced gun for game or clays.
