Heritage Guns' Comment

This very pretty little gun is a good example of the smallbore sporting hammerguns often purchased for children in the last quarter of the 19th Century. However, it has an unusually long stock for a gun of this gauge and, coupled with its sensible length barrels, 2 ½" nitro proof and sensitive restoration, it represent a pretty and highly 'shootable' gun for either game or clays.


The action is of traditional design and features:
Double triggers; Back action locks; Rebounding, low level hammers,
Top lever opening; operating a 'Purdey Bolt' by way of Greener style lever work;
Snap-on forend.
The breech can be opened with the RH hammer at full cock.
Gun weight 4lb 9oz Engraving style Fine scroll.
Trigger pulls measure approximately: Front trigger 4 1/2lbs Rear trigger 4 1/2lb
The original steel barrels are 28" in length, chambered for 2 ½ " (65mm) cartridges and are of brazed 'dovetail' lump construction with soft soldered ribs. Top rib is of the smooth, concave, game type.
Birmingham reproof for 65mm nitro powder cartridges in 1992.

Half pistol grip Stock and Splinter Forend are crafted from lightly figured, straight grain walnut. The snap-on forend features a horn tip and the stock carries a vacant white metal escutcheon and is finished with a 1/4" horn butt plate secured with engraved screws. The stock is lightly cast-off for a right-handed shot.
Lightly figured walnut
The 22 (approx) lines per inch chequering has been cut to a normal backlock design.
The stock is finished with a traditional linseed oil based preparation. This finish uses no grain fillers to achieve its deep, smooth lustre but up to 30 coats of hand rubbed oil.
