Severely corroded decorative brass clamp. What is it and how do I clean it?

[vhs07]

Here's a strange brass band clamp with what appears to be a worm gear tightener on it that came out of a local bay. The square shaft of the piece coming off of it is decorated with circles. It's heavily corroded from being in salt water, so I can't make out much more. I find it odd that this type of clamp is made of brass and not stainless.
Does this ring a bell with anyone? Also, what could I soak this in to help remove some corrosion? Thanks

Looks like it could be a oarlock for use in rowing a boat.

Paleo, I can't get your link to open

I thought oarlock too, but I don't see how it can swivel.

Don't know where that link came from...I didn't post it. But I just got rid of it.

Unless the whole thing was part of a mechanical swivel. Heck, maybe it's a telescope mount.

In the top row, second pic, I'm seeing something on the straight piece, 000000 or something, what is that?

That's just decoration. The more I look at it, the more decorations I can see. I'm going to try to clean it up some. ( suggestions ?)
As far as the oar lock, I don't believe it would be strong enough for one. I'm thinking is more of a bracket that held something in the round adjustable part.
Since it was found in the bay, I was thinking nautical, but down here it could be from anything.

Maybe a fire extinguisher mount?
