Reply To: US Navy Bell question
Here’s a site offering a bell like yours for sale. I’m sorry I don’t know enough to vouch for all they have to say about it (the first one on the site is the one like yours.) I do know that I’ve never seen a USN bell with an incised “USN” cast into it, the ones I’ve seen all had the USN engraved.
The second bell, on the site, with “smooth sides” looks right to me for a standard-issue type small USN bell that you would requisition out of the supply system.
