Heritage Guns' Comment

This hammergun represents a very good example of the small bore sporting hammerguns that were marketed primarily for young persons and ladies in the last quarter of the 19th century.
Undoubtedly made in the Birmingham trade for this respected provincial gunmaker, it is a nice quality gun. The original dark walnut is highly figured, internally the gun is very well finished and this coupled with the sensitive restoration makes it a very pretty and highly 'shootable' gun for either game or clays.

Presented in a contemporary, relined leather & brass case with a Heritage Guns trade label and some accessories.


The action is of traditional design and features:
Double triggers;
Stanton patent rebounding back-action locks with high level, ‘Hares Ear’ hammers;
Well carved percussion fences & rounded bar;
Top lever opening, operating a 'Purdey’ type bolt by way of Greener style leverwork;
Hacket type snap forend fastening.
The gun balances about 1/8” in front of the action knuckle.
 Engraving style Beaded border with stylised flower and scroll detail.
Locks signed ‘E. CHAMBERLAIN’ in a scrolling banner.
Some traces of original hardening colour and overall patination.

The original semi-pistol grip Stock and Splinter Forend are crafted from highly figured walnut,
the stock is lightly cast off for a right-handed shot and is finished with engraved heel & toe plates and chequered wood.
The forend has one small inlet repair to its edge and an engraved steel tip.

Highly Figured Walnut

The 22 lines per inch chequering has been freshened to its original 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.
