I have a Holland & Holland 12 gauge Hammer Gun, SN 21796, with 30 inch steel barrels choked about IC in the right barrel and Mod in the left barrel. It has 2 inch chambers. It weighs 6 pounds, has a straight stock with 14 LOP to a spurred steel butt plate and 1 DAC and 2 DAH. Shoots quite nicely with and ounce hand loads using RST 2 hulls. Top rib is marked SHOT AND REGULATED BY HOLLAND & HOLLAND, 98 NEW BOND STREET, LONDON.

Some pictures below.

I recently acquired the gun from a fellow shooter who purchased the gun in England in July of 2011 from a gun dealer in Leicestershire for 1600 British Pounds. Once in the US, it got a once over check that included per the work order:

Remove original, broken firing pin bushings and deformed firing pins. Carefully measure and make 2 new bushings to correct dimensions and Whitworth thread style. Make and fit 2 new firing pins, shaped and polished for best ignition right protrusion 0.060 and left protrusion 0.060 (longer lengths still produced pierced primers). Bushings were made to somewhat larger external dimensions for greater durability and ease of cleaning (1/4 head size), and all parts made of Brownells Fatigue Proof high quality steel, designed for high stress parts/uses.
Carefully cleaned out all inletting (butt stock and fore end), repaired 2 3 cracks at head of butt and strengthened all with thin penetrating glue and other clean up.

I had pictures of the gun with me at the Las Vegas Gun Show in January and showed them to a couple very helpful gentlemen. Based on my photos and the guns markings, proof marks, etc., it was made around the turn of the last century and was not manufactured by Holland & Holland but some other maker, probably in Birmingham and marketed by H&H.

If anyone would care to add any comments and what an estimated current value would be here in the USA, I would appreciate that. Its a delight to shoot and Im not planning on selling it. I would just like to add to its current appeal.

Thanks for any comments and I apologize for this lengthy dissertation.
