Either one will take a class 66 bobbin and a standard needle. (15x1)
I agree, I think it's a 66. I have one exactly like it that I got at an estate sale for $22.50 in much better shape than that one. Not to put down your find, just providing more info so you can make an informed decision about how much to pay.
