Exactly as shown. The original box is distressed, and has multiple stickers on the front (not shown).
The gauge itself is new.
I see many listings that put the numbers "04.573.01" in the title, though I don't know where they get them from (maybe from the Amazon listing, shown in the 2nd picture?).
I don't know anything about sailboating, sail rigging, etc. If you've read this far, then you probably already know what this is and what it does.
