I would highly, highly suggest making a trip over to the GreenKeys
mailing list. They know everything you could possibly want to know
about restoring a Model 33 ASR (and some things you don't want to know
as well).
They'll also more then happily point you toward a proper maintenance
set for the machine.
Not saying that the CCTech list is not the right place to ask, but
CCTech isn't a mailing list devoted almost entirely to teleprinters
(Kleinschmidt, Siemens, Creed, Teletype Corporation...).
Cheers,
Christian
