Here is the gist of emails from November 2007. The admiral isn't here right now. When she returns I'll see if she remembers any additional details.

The closest grate available would probably be the Seaward 70114. They are $15.35 each. They have two indexing bumps sticking off the bottom that would probably need to be ground off. You could also drill two small holes near each burner for the bumps to drop into. With some Shipmate burner styles I have heard that you need to raise the stove top up slightly so that the burners aren't taller than the grate.
