Looking for Mortise Bolt source

[SailorChlud]

Help! Does anyone know of a source for a Mortise Bolt with a 1" backset?

I had a chromed 1 inch backset bolt in the mahogany cabin door I refinished, but it was so corrooded it was unsalvagable.

I can only find sources for 1.5 " or 1.75" backsets, either here in the USA or England.

At this point I would take chrome or brass, keyed or not keyed. Any ideas?

I am trying to finish the cabin door, and have no way to keep it closed under way, without putting in some other type of door catch.
