I'm thinking of taking a stab at restoring a lever machine. I have a Londinium L1 which I love, but it might be fun to get an older spring lever with more history and character to bring back to life. Does anyone have suggestions about a good brand/model to seek out for this purpose?

I have been stalking all of the vintage restoration posts on the site for awhile and thinking the same thing. I am also curious about where to find a machine for restoration (it seems like ebay has some overseas, but not sure how that would work).
