I bought this compass at Traditional Marine Outfitters in Annapolis Royal, Nova Scotia, Canada. It is still filled with fluid. It is a Sestral brand. The compass card has "No. 9007" near the south arrow. It is about 8" square. There are no other markings. It definitely has seen a few days on a boat.
I looked at various compasses and decided this would look sufficiently salty for No Strings Attached.
I now have to figure out where to mount it. It came without a cover but that is easy enough to make a replacement. Another question is whether I should clean it and how.
