I totally agree with Leon.
As for cabinet I like to use
Cleaning and Reviving furniture(Sewing cabinets) for reference.
I have read that the "nose" on these machines can be a major hassle and is generally advised not to take it apart. Many of the metal pieces can be removed and cleaned and polished.
A couple of other links that might help are

Cleaning and repairing the Shellac clear coat on Vintage sewing machine heads I think I would start by just wiping the machine with a lot of sewing machine oil and cotton balls.
