Heritage Guns' Comment

This gun represents an unusually fine condition example of the early sporting centrefire hammergun that displaced the pinfire guns of the 1860's and '70's. The 'Jones Rotary Underlever' exhibited here was hugely successful, being used well into the 19th Century especially for double rifles, big bore shotguns and wildfowling guns as it is one of the simplest and strongest actions ever devised. All gunmakers, both modest and most venerated, utilized it extensively during the transition from muzzle loaders to breech loaders and if Henry Jones had only maintained the patent protection on his design, he would have become a very wealthy man. The gun balances almost exactly on the hinge pin and with substantial traces of original colour hardening still visible on the action, coupled with our sensitive restoration, it is a very pretty and highly 'shootable' gun for either game or clays.


The action is of traditional sidelock design and features:
Traces of original colour hardening on the action,
Bar action sidelocks by Stanton,
Rebounding hammers,
Sprung strikers,
'Jones' rotary underlever opening incorporating a tensioning spring,
'Wedge' forend fastener,
Double triggers,
All screws & pins in perfect order,
Yellow metal barrel bead and stock escutcheon
Gun weight 6lb 10oz
Engraving style Fine border & scrollwork.
Trigger pulls measure approximately: Front trigger 5lbs Rear trigger 4 1/2lb
(these can be regulated to suit the buyers requirements)
Balance point is almost exactly on the hinge pin.

The bold Damascus barrels are 30 1/4" in length, chambered for 2 ¾" (70mm) cartridges and are of brazed 'dovetail' lump construction with soft soldered ribs. Top rib is of the smooth, concave, game type.
There are some minor vestigial pits in both tubes but only one pit of any substance: 3" from the breech in the right barrel. None of these pits represent any hazard providing appropriate cleaning is carried out after use.

The Straight Hand Stock is slightly cast-off for a right-handed shot and is finished with a horn butt plate (small chip to toe of plate). The Splinter Forend has a 'Wedge' (aka Cross Bolt) fastening and a sculpted horn tip. Both the forend and lightly figured stock are most probably the original walnut.

The 18 lines per inch chequering is cut 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.
