Heritage Guns' Comment

This gun is a fabulously finished and specified example of the small bore hammerguns often purchased for children or wives by indulgent patriarchs and represent a very rare opportunity to acquire such a fine small bore gun from this highly respected maker. Although provisionally dated to the 1875-1887 period by the original proof marks, because of their faintness, we can only definitively date the gun by the top rib address which was pre-1894.
The action is profusely covered with best fine foliate scroll, with some Celtic robe border and this coupled with our sensitive restoration makes it a very pretty and 'shootable' gun for either game or clays.

Fabulous value at only 5990

The Straight Hand Stock and Splinter Forend are crafted from highly figured walnut. The stock features a vacant white metal oval and ebonite chequered butt plate secured by engraved screws. There are two small inlet repairs to the lower horns to repair wear and it is lightly cast off for a right-handed shot. The forend has a finely engraved steel tip and catch escutcheons and has three small inlet repairs to its edge.

Highly Figured Walnut Stock & Forend

The 18 lines per inch chequering is freshened to a normal sidelock 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.
