Good to see you posting, Kyrie.

Best,

Are the original barrels unusable or missing?
If you have the originals, are they marked in mm, and if so, what are they marked?
Do the chambers measure 2" and how did you measure them?
What is the date code on the barrel flats?
Does the catalog repro show the grade?

Kyrie: during what period was the chamber marked c.410.50 ? Thank you.
Shotgun chamber in Spanish is recámara; in Basque ganbera
Barrels in Spanish cañones

What happened to the original barrels?

I'm not aware of any period during which that style of marking was customary. But then this is Spanish shotguns; hang around long enough and one can see just about anything.

The original barrels are long gone, trying to help revive this old gun for a customer of mine that had it passed down from grandparents. I do have a matching 12 gauge to compare but no original .410 barrels. I’m assuming it’s 2” chambers purely by the 410. 50 stamped on the receiver which I believe to be 50mm? Would an identical style barrel chambered 3” possibly be usable?

Even better. This, technically, is not your problem.

The chambers issue is irrelevant. The relevant point, as Kyrie has duly noted, is parts are not interchangeable on Spanish artisanal shotguns.

Full stop. Go back and read it again.

There is no warehouse full of fully fitted spare parts for old Spanish double guns. They were typically built to order, with the internals fitted by skilled labor. A gun fitted up on Monday would have no interchangeable parts with one finished on Friday. This was a cottage industry, with suppliers turning out rough parts for a manufacturer that then fitted them by hand. In later years, some of the manufacturers might have had higher production of models that featured production machining, but, your gun is not in that group.

Noted by no one at this point in the discussion is that barrels are literally the heart and soul of the gun. If they aren’t there, you are facing a huge, uphill battle to get even a machine made gun (think Beretta, SKB, Savage, etc) up and running, more so if the gun is obsolete. An artisanal gun, from a small, long gone maker will be close to impossible. Were you to find a set of compatible barrels you would need to enlist the services of a good double gunsmith. This guy is not the same as the guy who blows chokes open from the front of Mossberg 500 barrels, and replaces parts on similar guns. He has a skill set that doesn’t come cheap.

All that said, good luck. Impossible might be too strong a word, but, you are pretty close to it.

Best,
Ted

If you have to replace both barrels and fore-end it woild be far easier, and probably much cheaper (even if you have to pay top dollar for it) to find an buy a complete example of a similar gun.

If you find its twin it is improbable that the barrels would interchange without a great deal of work.

These videos (shot in Grulla's workroom) will give you an idea of what you are up against.

I do have the numbers matching fore-end to the receiver just no barrel assembly unfortunately.

That is one problem solved.

I wish you luck is your search for a barrel set that might be adapted to fit.

There are,of course, barrelmskers, who could build you a new set of tubes but the cost would be prohibitive.
