Your 185 is the younger sister to your 99 - basically the same machine in a more modern case. I'm not home right now but I think she takes a class 66 bobbin and standard needles. I do believe they are all green (oops I stand corrected - apparently some are beige). I have done something to mine, but when I tested it right after I got her, she sewed fine. I have seen comments that they are noisy, but I don't remember mine being noisy. Enjoy your new toy.
