I found this at the beach where lots of sand has washed out and finding tons of fishing weights. I suspect the remains of a wrecked fishing boat is in that area and that this might be part of it. I just don't recognize it as anything I've ever seen. Weighs close to 10lbs and as you can see in one of the photos, there's some small gears inside one end. The other end has what appears to be a grease fitting inside a cupped area that has a smooth black finish. The outer shell has what I thought initially was a separate ring with threaded square lugs. It turns out that that ring is not a separate piece, but, has just a section that is separate, but, not all the way around. In the area where it is split from the housing, there is a cinch bolt that would tighten that ring like a hose clamp. The outer smooth ring on the end that has that black cup looks like it might possibly rotate, but, it's corroded tight at this point. Inside the main housing is that gear assembly (kinda like a clock mechanism) and a brass "bellows like" item.....looks like a stack of records or CD's. What do you figure?
