Argentina Cast Brass Barrels

[BoomLover]

Anyone have any experience or info on Argentina Cast Brass Barrels. 21 inches long, 40 pounds, 1 1/2" bore, steel liner, muzzle loader, stamped 03 27, and H.M.S. Victory, 1805, Black Powder Only, Made in Argentina, on a Naval carriage with steel rimmed wheels, quoin, ropes, and ram. Paperwork says "cast of Foundry Cannon Brass, same as Forged Bells" and 400/500 grains 1Fg B.P. recommended. I'm guessing mfg 2003, barrel #27. Any info would be helpful. Thanks, BoomLover

Maybe from Réplicas de Armas Antiguas?  A forum sponsor.

cast of Foundry Cannon Brass, same as Forged Bells

I'd be interested to hear a metallurgical explanation of that, because I think something was lost in translation.  Bells as I understand are considerably higher in tin content than gunmetal bronze (90/10) so I don't know what is meant by the marking.

And for that matter, "forged bells?"

Not sure at all what they are getting at.

bells often have between 20 and 30 percent tin ,
it depends on what sound you want in it .
the more tin the higher frequency in the tone .

more tin make the alloy harder and more fragile .

if bell bronze was used for a cannon ,
I sure wouldnt want to be close to it when fired .
its way to brittle .

a large bell with low tin content will have a low tone
smaller bells with higher tin content will give higher tones .

Antique Weapons Replicas - Prof. Osvaldo Gatto

there is a long thread about his use of non seamless tubing in these, not  N-SSA approved,

I believe after a long discussion on this board he has changed some manufacturing techniques

including the use of seamless tubing, this cannon is pre seamless tubing by the date.

Thank you for all tips,

But it seems that people not read correctly what I write on many occasions.
I would be very frustrated by repeating the same thing over and over again.
""From now on I do cannons with seamless tube""
Do not be difficult to understand this, I say this several times before.
Not having sense a forum if not then read the answers.
You have a cannon of my manufacturing and still be alive and funny.
You can shoot golf balls without any problems with that cannon.
O.G.

You Fellows are right, it was a Prof. Osvaldo Gatto Barrel, on the Naval Carriage. Thanks for all the replys and I did not buy it! Looked nice, but best to not take a chance. BoomLover
