What parts are compatible with my Silver SK101 knitting machine?

Im new to machine knitting and I got my machine used, so Im not too sure what Im necessarily missing from it. I dont have any weight claws, cast on comb, or a needle selector. I do have 2 lengths of cast on wires, a carriage, and an arm to the carriage. I dont know what it needs in order to get going on it, and furthermore I dont know what I can order that would fit my machine. There doesnt seem to be a whole lot of info online, though I was able to find a manual. Do knitting machines tend to have universally sized parts, or no? I think mine is a 45mm gauge. I cant seem to figure this thing out tho! Its kinda driving me up the wall!
