I have this same machine. I bought it new in 1966 for $150. It has mended hundreds of pairs of Levis and overalls. It was a very good machine. It is a big noisy, but good. It uses 66 bobbins. The good news, they are available everywhere bobbins are sold. I buy all my repair parts at Sew-Classic.com. I use PayPal and there is never any issue with that. If you don't have a credit card, then Jenny would probably hold your order for the check to pass. Either way, you will get your order it tip top shape and as quickly as it can get there. We have been ordering there for 7 plus years and find Jenny quite delightful.
