I happened upon one of these machines. It had a bit of rust and nearly everything was locked up, but a couple of days of Kroil and carb cleaner and all the stuck bits are moving smoothly and it's printing!
It's a pretty neat machine. Small footprint for basically most of the guts of a Model 15.

I've been using scissors to cut normal 5-level perf tape in half which fits through fine, but would like to get a reel or two of the real stuff if anyone has some.

I also am missing a few keytops. They are the same design as a Model 15.
I'm looking for:
R, T, O
[Return]
Z, X, M, [Line Feed]

A few before pictures. It looks a lot better now.

Thanks!
