Someone I know purchased this barrel at an auction. It was represented as coming from the ocean floor but I don't know where.
It's pretty rough.
Here is the description from the auction house.
Six-Pounder Iron Naval Cannon "Hope Furnace - Rhode Island" Circa 1800. A rare British style 6-pound naval cannon that has been overstruck "H.F." for the Hope Furnace Foundry in Rhode Island. With a shortage of both foundries and cannons, the American Navy utilized captured cannons from British, French and Spanish frigates that were taken as prizes by American privateers operating on the high seas. They would in turn use these same cannons to arm American merchant vessels sailing from New York and Boston. It is 62" in length with a 3.75" bore and is marked "H.F." on the breech.
I currently have the barrel in my possession. It has not been through any conservation procedures.
I believe it will continue to deteriorate.
The barrel is 62" long and I am told it weighs 850 lbs.
Here are some pictures.
The markings "HF" described above can be seen here.
I was asked to build a nice naval carriage for it. I used 3" thick oak.
Splendid results, Michael! I sure hope that you gave your wife's back and shoulders a nice rub after she cranked that Come-Along handle for 20 minutes to get the Cannon Tube up high enough for mounting!!

Smokin my pipe on the mountings, sniffin the mornin cool,
I walks in my old brown gaiters along o my old brown mule,
With seventy gunners beind me, an never a beggar forgets
Its only the pick of the Army that handles the dear little pets - Tss! Tss!
My lovely assistant is one tough girl. She is on the other side of everything heavy that I have to pick up.
She certainly was there with hands on the barrel as I lifted it with the engine hoist.
Barrels that are badly corroded need to go through a process to stabilize them. It involves soaking them in a solution and using electrolysis to stop and reverse the rusting process. It can take years. All the Alamo cannons that were recovered went through this process at Texas A&M.
The carriage weighs about 175 lbs.
