We found this while at a beach in Maryland after a big storm. It looks like it’s some kind of squeegee thing, assumingly for a ship considering the location and material.
The hole is threaded and with the direction of the writing, I assume a pole goes inside to act as a handle.
There looks to be a slot where perhaps a rubber or other softer material would be slid in to.
It appears to be brass and is non-magnetic. We’re thinking about restoring it. Either way, we couldn’t read enough information on it to tell who made it.
A Google image search doesn’t bring it up either. Google brings up “Rope Cleats” made for tying a ships ropes to, but this has distinct features that make it appear to be an incorrect match. For example, the angles of the slopes.
In case it helps another searcher one day, here are some pictures.
