Heritage Guns' Comment

This gun is a lovely example of the famous Jones' Rotary Underlever that was so commonly used on all types of break action guns right up until the early 20th Century.
However internally this gun is anything but common. The locks, supplied by Stanton, are built on his extremely rare second rebounding patent which is a design specific to rebounding conversions where the normal rebounding effect of the mainsprings passive arm cannot be used. The gun also features 'loaded indicators', very similar in appearance to the 'cocking indicators' of the famous Dickson Round-actions. These conform to the 1865 patent by WM Scott and so it is reasonable to assume that the action was supplied to Maloch by Scott. The action and locks display a substantial amount of original hardening colour which sets off the beautifully executed bold foliate engraving and fine wood.
All the above, coupled with excellent barrel and stock dimensions, makes her a mechanically fascinating, very pretty and safe gun for either game or clays.

Considerable original hardening colour;
Double triggers;
Percussion fences;
Loaded indicators;

The Straight-hand Grip Stock and Splinter Forend (thought to be originals) are crafted from well figured walnut. The stock features heel & toe plates, secured with engraved screws and is lightly cast-off for a right-handed shot. There are two near invisible bruise repairs to the upper horns. The forend features a horn tip which appears to be an antique replacement for a previous steel tip. There are four medium sized inlays to repair edge damage and a circular inlay to replace the forend securing pin.

Well Figured Walnut

The 16 lines per inch chequering has been refreshed 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.
