Heritage Guns' Comment

This is a superb example of a Best London sidelever hammergun from this highly respected gunmaker, made when hammerguns were at their zenith in terms of design and aesthetics. Over the last decade, the sidelever has become the most sought after operating mechanism by collectors of antique shotguns and this represents a fine opportunity to acquire one of these lovely guns. The 30" TIG sleeved barrels have been proofed for 2 ¾" nitro cartridges and this all adds up to a very strong gun that is a joy to shoot and should give many years of service on game or clays with normal maintenance.


The action is of traditional back action sidelock design and features:
Side lever operating a 'Purdey Bolt' which engages the rear lump by way of lateral projections,
Double triggers,
Rebounding back action locks
and Anson's push rod forend catch.
Gun weight 6lb 11oz
Engraving style Best fine foliate scroll, 'STEPHEN GRANT'S PATENT' engraved on the sides of the action and 'PATENT' in an oval on the top of the breech. No. '1' is engraved on forend, trigger guard and top rib.
Trigger pulls measure approximately: Front trigger 3 1/4lbs Rear trigger 4 1/4lbs
The TIG Sleeved Steel to Damascus barrels are 30" in length, chambered for 2 3/4" (70mm) cartridges and are of brazed 'through' lump construction with soft soldered ribs.
Top rib
is of the smooth, concave game type.
London reproof for 70mm nitro powder cartridges in 2012.

The fine 22 lines per inch chequering is freshened to normal sidelock pattern.
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.
