Fulton-

Are you referring to the discussion that has been going on over at the DoubleGunShop.com site?

Perhaps you could refresh us here on what's going on with your nice rifle, Fulton.

For the sake of lubricating this conversation, here are some images of the rifle Fulton has been asking for information about over at the other site.
There is also an incomplete assortment of tools associated with the rifle (I didn't bother linking images of all of them here - think bits and parts of a BPE cased rifle kit), the coolest of which I have included in this series - which I believe to be a mould for 'grease cookie' lube wads. I haven't seen one of these included in a brit BPE rifle kit before. The other tools are typical card punch, hollowpoint pin for a mould (mould is absent) etc.
No maker's case, no maker's information.

What Fulton does know is as follows:
(quoted from his source site)

Fulton's Rifle Page

It's a Holland & Holland doubles gun.
It appears to be a 50 cal. although it is NOT stated on the gun.
The barrels are rifled and in good shape.
The serial # is 8594
Engraved on the side of the gun: "Charge 5 Drams - Case 3-1/4 Inches"
The address on the gun reads: 58 New Bond Street, London
Also engraved on the gun: "Winners of all the field trials - London 1883"
The gun came with no case but did come with a number of reloading tools that I can't identify. (See below)
There's no model # on the gun. There's a number on the bottom of the barrels: " H122"
The gun is not in good shape... lots of scratches on the wood, some pit marks on the steel, but looking down the barrels, they look OK.
I can't get the gun open.. the lever (on the bottom of the trigger guard) is stuck, unless there's a trick to opening it.
I'm trying to find out a little history on the gun, and age.
I would like to identify the reloading parts.
Would this gun use black powder ???
Any thoughts on a value ????
Your help would be greatly appreciated...

Fulton, I'll reiterate some of what was noted over at DGS with a quote from 400NitroExpress which pretty much sums up an introduction to the rifle.

"Looks to be a Holland No. 2 Grade Hammerless LOG rifle in .500 3 1/4" Express. It's a black powder gun. The charge marked is the 136 grains of black that was normal for that cartridge, which most commonly used a 440 grain lead bullet. It's a useful cartridge, and pleasant to shoot."

Also noted over there is the fact that what he's got here is a valuable (even though it's been mildly butchered) and rare double rifle that needs the attention of a highly qualified double rifle mechanic/gunbuilder like JJ at Champlin Arms.

Y'all can take it over from here.
