Heritage Guns Comment

This gun represents a good example of the early hammerless guns that were becoming more accepted in the last quarter of the 19th Century and a rare chance to buy a gun retailed by this little known gunmaker. The sensitive restoration makes it a very pretty and highly 'shootable' gun for either game or clays.

WE REGRET THAT THIS GUN IS NOW SOLD. IF YOU ARE SEARCHING FOR A SIMILAR GUN, PLEASE CONTACT US.

The action is of traditional back action design and features:
Double triggers bolted by an automatic top tang safety slide,
Back action locks with 'barlock' lockplates,
Top lever opening operating a 'Purdey Bolt' by way of a 'Scott Spindle',
Roger's cocking levers,
Snap-on forend catch.
Gun weight 5lb 2oz Engraving style Border with scroll details.
Trigger pulls measure approximately: Front trigger 3 ½ lbs Rear trigger 4 ½ lbs.
The Damascus barrels are 28" in length, chambered for 2 ¾" (70mm) cartridges and are of brazed 'dovetail' lump construction with soft soldered ribs. Top rib is of the smooth, concave, game type. London reproof for 70mm nitro powder cartridges in 2006.

Straight Hand Grip Stock and Splinter Forend are crafted from straight grain honey coloured walnut. The replacement stock has a very slight cast off for a right-handed shot and is finished with a chequered butt.

Lightly figured walnut stock.

The 20 lines per inch chequering has been recut to the normal back lock design. 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.
