doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com looking for help pricing a large bore sxs

Well as the title states.

Is there a market for this type of old gun and if yes what would a guy expect would be a reasonable value......?

also

Looking for any additional info that the experts out there can provide, Lord knows I no very little when it comes to punt guns.
or even if this is truly a punt gun, maybe its just a really large duck/market gun.

What I know so far, the locks are Joseph Golcher and that Golcher was an American lock maker, maybe he was a gun maker as well I do not know.

The barrels are British proofed in the era of good old King George and with crossed staffs under a crown.

There are markings on the underside of the barrels, probably inspectors marks of some kind but I do not know and am hoping you experts can help shed some light on the whole thing.

I have included a pic of the barrels with a set of 410 sxs barrels for comparison.

I would love to know who the maker was but I suspect that will not reveal itself with the info we have, the british barrels and American lock is very interesting and I would like to know more about that, as well, I do not have a clue of potential value of these kind of guns or if there is even a market here in North America, so any views on that would also be welcome.

You can still waterfowl with 8 bore in the UK.
There is a vibrant market in punt guns They always go for solid premiums

I couldn't tell from your pictures if you have a large bore shotgun or if it is actually a punt gun.

yes clapper, i am trying to determine that as well.

I think the gun is probably around a 4 bore at the breach but hard to determine. any ideas on how I can tell.....? or diagnose...?

Shoulder fired vs mounted in a "Punt" is probably a good one.
Though you could have a swivel mounted gun.

In this month's "The Field" magazine, a fellow was shooting 2oz of BB shot from an 8 bore single.

I'm not an expert, people on the eastern shore are more knowledgeable about them than a lowly Saginaw Bay waterfowler, but there is a practical charge limit for shoulder fired shotguns.
Once you go above that, it has to be mounted to the boat.

I'd start to determine that by going to the muzzles first ............ and measuring.

SRH

I suspect it is a shoulder mounted gun, muzzles measure 1.820 across both barrels, .750 on the inside and .910 outside at the muzzle.

At the breach, the barrels measure 2.500 across both barrels outside and each barrel measures 1.320 outside.

Overall length is 57 inches and she weighs in at around 15 pounds.

Any way to mount it to the boat?
Trunions or brackets anywhere?
So, 3/4" bore at muzzle? That's a nominal 10, but what about at the breech?

Sounds like an 8 gauge fowler to me.

Yes clapper you are probably right. It is likely an 8 bore gun, there is no way to mount it on anything it is definitely a shouldered gun. As stated earlier breach measurement from the outside is 1.320, cannot measure the inside, so i'm guessing logically it would come in around an 8 bore maybe a 6 but hard to tell.

any value to these guns....? and who is buying them and for what reason.....?

If this gun has a .750" choke, it most certainly is not a 4 gauge or an 8 gauge either. Sounds like it may be a heavy 10 gauge waterfowl gun with rather long and heavy barrels... not a punt gun. Since it is a percussion gun, and may have been built before choke boring was common, it could be an 11 gauge.
