You can get them at West Marine. Only they
are not brass (or even bronze--plastic), not armored
(plastic), and not round.

I'm thinking of replacing my Europe style windows with ol fashion port
holes.

Anyone know a source for 13 solid brass military type port holes?
US Navy surplus would be ideal. 16-22 inch with D solid covers, opening
armored glass type.

Thanks
