Oh, oh, I can help on this one! The model is a 27. The decaling is known as either the Sphinx, Memphis or Egyptian. You'll need a 3/16" belt and the needle is the common 15x1. Bobbin is the S228 and the shuttle is 8327.
My teachers/mentors will be along shortly to grade my answers :-) I'm so hoping I passed.
(I recently came into custody of one of these darlings.)
Enjoy,
best,
