British made cannon. 1756. See anything?

The cutting tools that finish turned/bore it were forged on an anvil.  The stamps that dated it were forged.  The engraving tools that carved the inscriptions on the midsection were forged.  The tongs that held the crucible while casting were forged by a blacksmith.  The chisels that turned the wooden pattern were forged.  The sawmill that made the wooden carriage had some iron and steel parts, just guessing here... made by a blacksmith?  The miners that mined copper and tin ore may have had some iron tools.  Hammers that broke up the ore at the smelters' may have been iron. 

And it seems to have some forged iron carriage fittings.  

Does it weigh 555lbs?

The # on the breech plug are stone weight.  

I wonder if the Cannon on the USS Constitution, from Principio Iron Works, have stone weight.

I don't know about stone weight.  I was Iinformed it is English hundered wight. It explains how to figure the weight same as the Peter Wright anvil.

And this is why I enjoying logging on.

Sure beats a job. About some of the views you guys are talking about, I only see one pic, did I lose out on another vote?

Frosty The Lucky.

16 ounces to a pound ( oz and lb )

14 pounds to a stone ( st )

112 pounds to a hundredweight ( CWT )

anvils here are often marked as hundredweight, quarter hundredweights and pounds ( dont know of much else that uses quarters)

before kg people here were weighed in stone and pounds

2 stone = 1/4 hundredweight (28 lbs). 

Horseracing anyone ?

Today at the racetrack (Saratoga in New York) I leared what stone weight is from talking to the famous track announcer Tom Durkin. 

Funny how things work out.

I worked with an astrophysicist from England, (well Scotland/UK) that weighed himself in stone, and just today I was reading Terry Pratchett's "Hogfather": it mentions "She's a good 14 stone if I'm any judge"

Most people over here (England) use both metric and imperial if you're weighing yourself it's in stones pounds and ounce, cars and scrap metals are weighed by the ton but food is sold by grams or kilo's but beer is sold by the pint or 1\2 pint most use feet and inches for most things, but if you want the accuracy you swap to metres/ millimetres. After working I construction I can use whatever measurements are thrown at me it makes no odds. But it was a little confusing when I first started out.

The cannon description didn't say. It did describe the weight which was same for a Peter Wright anvil so I assumed it is what I know as English Hundred Weight ......if that is correct.
