Erm, not very similar to the FM-10. But, the original FM, yes.

Anyway, to the OP, wish you luck with the sale, and, don't worry about the username change. When I got rid of my F3P last summer, I changed my username from "John_Nikon_F3HP" to "John_Nikon_F". I could change it back, now that I have the same F3P back, but I won't. I love my F too much.
