It's a Singer Sphinx Reproduction.

What kind of parts & accessories should I buy from let's say... sewclassic.com?

Thank you.

There's a loaded question.
Some of those are old enough you can almost get away with "vintage". If I had one to sell I would explain that it's not quite the same as the truly old ones though.

Is it in running condition? What do you plan to use it for? It should be a low shank machine, use class 15 bobbins and regular 15x1 needles. If you want to darn or FMQ, a hopping foot is good to have. Do you have (or need) a buttonholer and set of feet for it? Ebay is also a good bet for feet. Extra bobbins are always nice and Sew-Classic sells a far better quality bobbin than the Singer branded blister packs at places like Walmart.
Hope this helps,
Rodney

Yep Sew- Classic is a good place especially for your bobbins. Your machine should take class 15 bobbins, standard needles and low shank feet. From there just figure out what you are planning to do it and choose feet that are made to do the work!
