Your tube is a 30 pounder (4.2 inch) Parrott, with a weight of 4220 pounds. It was out of the West Point Foundry (WPF) and bears a registry number of 348. It was produced in 1864, and inspected by Richard M. Hill (RMH).
That's why I asked for the follow-up photo - you had me scratching my head as I perused my database for know coastal defense tubes in Michigan. We are talking Parrotts!

My wife was in an antique store in Marshall Michigan and I had to keep busy for an hour so walked over to look at the cannon. It was look at the cannon or visit the magic museum and I did not want them to "saw me in half".
Also, there should be a "U.S." on the barrel and possibly a patent stamp at the base of the breech. There is an exceptional book on the casting of these monsters from the Images of America series.
Fort Pulaksi performs live-fire demonstrations with a 30 pounder Parrott; pretty amazing to see and I'm sure you can look at google images and find some postings. I have some photos somewhere of night firing of the 30 pounder that came from a fellow Ranger down there.
The West point Foundry made Parrotts as large as 300 pounders.
By live fire, I meant firing a solid shot at a target.
The Parrot I observed hit a bullseye of a 3-ft target at 1/4 mile. The kick was powerful and took 4 or 5 guys to roll it back into position through the mud.
