Heritage Guns' Comment


I have a great affection for Blanch Back-action SLE’s as my father shot with one from his early 20’s until he retired from shooting at the age of 85. When I say ‘one’, I mean he used the same gun for 60 odd years! It may not have seen a huge number of shots but it certainly saw huge amounts of weather and is still in good functioning condition in my guncase some 20 years later.
Blanch had a great affinity for back-actions, the vast majority of their sidelocks being such right up to the early days of the C20th and their engraving was also most distinctive. At this time their engraving can be divided into three distinct styles: areas of ‘Creeping Vine’ with foliate scroll, an open pattern with around 70% coverage which adorns this gun; classic bouquet & scroll, about 85% coverage, used mainly on their Grant style sidelever hammerguns and lastly 100% coverage bold foliate scroll on their most ornate guns.
This is a most attractive gun with its bold engraving style and, given its fine balance, interceptor sears and strong stock, it would make an excellent gun for upland game or clays.
Presented in a relined, contemporary leather case with original Maker's label and some accessories.

The Original Straight Hand Stock and Splinter Forend is crafted from well figured, straight grain walnut. The stock is cast-off for the right hand shot, features a vacant white metal oval and a 1” leather covered recoil pad.

Well Figured Walnut

The 20 lines per inch chequering is refreshed to the normal J Blanch design of fully chequered forend with a narrow unadorned border and a stock pattern that closely follows the outline of the lock plate.
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.
