Heritage Guns' Comment

This is a very clean example of a London sidelock from this highly respected gunmaker, made in the heyday of the British gun trade, complete with its 'Maker's case and some accessories.
The sleeved 28" steel barrels have been reproofed for 2 3/4" nitro cartridges and the original stock and forend are in fantastic condition for its age. This all adds up to a beautiful and 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 sidelock design and features:
Top lever opening,
Mill's sliding bolt engaging a top rib extension and Purdey Bolt operated by a Scott Spindle,
Double triggers bolted by an automatic top tang safety slide,
Back action bar locks,
Roger's cocking levers,
H&H style interceptor sears,
Anti-friction rollers on main springs
and Anson's push rod forend catch.
Gun weight 6lb 6oz
Engraving style
Beaded Border and Foliate Scroll with Geometric Foliate Panels
Trigger pulls measure approximately: Front trigger 3 1/2 lbs Rear trigger 4 lbs
The soft-solder sleeved damascus to steel barrels are 28" in length, chambered for 2 3/4" (70mm) cartridges and are of brazed dovetail lump construction with soft soldered ribs. Top rib is of the smooth, concave game type.

Straight Hand Stock and Splinter Forend are crafted from well figured walnut. There is one edge repair to the forend wood and 1 repaired settling crack behind the right lock plate. The stock is cast-off for a right-handed shot, features a vacant white metal oval, well defined drop points and thin horn butt plate secured with engraved screws. The forend features a finely engraved forend tip.

Well figured walnut

The 22 lines per inch chequering has been freshened in a 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.
