Hi

This M.H. tube that I've got is made by Cannon LTD in the 80's. Any one know about Cannon LTD other than the owner and his wife are both dead?

I owned a 10 pounder Parrott Rifle that they made. I visited their shop in the late 1990's and think they made a top quality product. One of the best on the market In my humble opinion.

You're sure it is cast iron?

They're obviously more concerned about safety than certain other orgs. My hat's off to them.

When I purchased my gun in 1998 Cannon Limited offered several types of barrels. They offered solid cast with a drilled bore and pressed sleeve. Also one with a sleeve cast in place with a patented process to ensure the sleeve was centered.
My Parrott had a cast in place 1/2" liner with a 3" bore.
My 1996 catalog shows a full scale 12 pounder mountain howitzer offered 3 ways;

1. steel lined ductile iron barrel (cast in place)
Price - $1799
weight 275 lbs.
length 37"
bore - 3"
liner - 1/2"

2. solid cast ductile, drilled, then steel lined
price - $2199
weight 275 lbs
length 36"
bore - 3"
liner1/2"

3. solid cast steel barrel, no liner, ASTM A148 grade 9060 alloy
price - $2695
weight 280 lbs
length 36"
bore 4.62"
powder chamber - yes

look at the above descriptions. Mainly length and bore size. You may be able to figure out what barrel you have. Keep in mind all info came out of a 1996 catalog.
If your gun has a liner you should clearly be able to see it at the muzzle.

Gary,
I just assumed your tube is full scale. It was offered in 1/2 and 3/4 scale in the solid steel barrel only. I have that info if you need it.

Hi

ZULU thank you very much this is the kind of info that I'm looking for, and yes it is full scale lined but at the muzzle is .040" out of center.
Now any other proud owners of Cannon LTD cannons?

Gary,
If it is lined, what is the length?
37" equal cast in place liner.
36" equal cast solid and pressed liner after boring.

Gary,
Don't know if this is the kind of info you need but here it is.
Ductile iron has a tensile strength of 65,000 pounds, a 45,000 pound yield, and has 12% elongation.
That is the claim out of the Cannon Limited catalog. I personally don't know much about that stuff.

Mister Z
Good info. the cannon is 100 miles from here so running out and checking is out , I'll send this information to the new cannon battery and have them check it out.
When you said duct. iron I figured that the tensile was about 60 or so that's what you would expect. Any spec. on the liner? Again thank you.

I believe early Cannon LTD barrels were pipe cored cast iron pieces.

Hi

As I was inspecting the tube for the first time I'm sure that I saw no sign of a welded seam or the machining off of one. there is the sign of a light covering of black scale but not enough for being poured in place. I have'nt head from the boys yet about if it is 36 or 37" long .
