Guns' Comment
This lovely old hammergun, made by one of London’s smaller but
highly respected gunmakers, is a fascinating example of how many
guns moved through generations of family and social strata during
their many decades of service. This particular gun was entrusted
to me for restoration by the family that had owned it since new on
the condition that they remained anonymous and that its history
would be shared with the new owner. It is known that it served as
the premier shotgun of the head of the house for at least two
generation and was then turned over to the gamekeeper and so to
his son when he succeeded him. When finally retired from service,
it returned to the family gunroom and was left to collect dust at
the back of a cupboard. It shows much honest wear from countless
hours carried over the arm in all weathers but where protected,
the quality still shines through. Three interesting details are
that internally the action carries the Blanch name stamped in bold
on the back of the action alongside the actioners name, Charles
Drydon, the locks were neatly converted to ‘rebounding’ in the
1880’s and the Purdey patent use mark was engraved with the
initials ‘PP’ not ‘JP’. All the internal parts carried the patina
of the intervening years but this was only surface corrosion in
the main and I have painstakingly polished all the parts before
reassembly. The barrels have survived amazingly well: passed 2 ¾ “
nitro reproof in 2024 and the very fine damascus rebrowned
beautifully. The ribs didn’t even need relaying! Also the superb,
dark French walnut stock is in fine shape and we have refreshed
the chequering to its original pattern. With its fascinating
history, lovely wood and fine barrels, it would be a privilege to
see the gun in action again with a new custodian for another
generation or two. Presented in a canvas and leather trim case,
relined with forest green baize, fitted with some accessories and
a reproduction Maker’s label.
