Hi - I’m trying to find anything I can about this clock. It looks to me like it belongs on a ship? But I know very little about naval vessels - or clocks, for that matter… any ideas? Thank you! It’s 7” (18cm) in diameter and 2 3/4” (7cm) deep. Appears to be brass. Looks like the frame unscrews, but I can’t budge it. Can’t find any signatures on the face or the case.
