Guns Comment
This gun is a well executed example of the conversion
of a high quality muzzle loading gun to centrefire breech loader,
a service offered by most gunmakers during the transition period
of 1850 to 1870. The original material was a best quality gun
by this famous gunmaking firm, established by the elder brother
of the even more famous Joseph Manton who was our gunmaker's apprentice.
Components from the original gun are the barrels, ribs and butt
plate; most probably the stock and locks and possibly the triggerguard.
Great care has been taken to duplicate the engraving of bold scroll
and game scene on the action and, although the conversion is arguably
not of 'Best' quality, it has been sympathetically undertaken
by someone who knew their trade. The barrel conversion has been
done with 'Table Lumps', where the barrels are floated onto a
sculpted concave table/lump monoblock that wraps round the lower
third of the tubes, and the ram rod tubes have been replaced by
neat damascus inserts into the bottom rib. At some time the stock
has suffered some damage at the hand but a professional repair
has been carried out including an inlet bracing piece under the
trigger guard tang and the repair is virtually invisible once
the gun is assembled.
We would draw your attention to the fact that
this gun features Non Rebounding Locks and it should be used only
by those experienced in this type of lock and under controlled
circumstances.

The stock is finished with a traditional linseed oil based preparation
as used on best guns by one of the top English makers. This finish uses
no grain fillers to achieve its deep, smooth lustre, only many hours
of alternate build and flatting off of the surface.
