I'm a long way from good at this but I have one that looks a bit like yours. I learned on U tube.Just type in long bobbin sewing machine. If you look on the right side front of your machine you might find the serial number. Singer carries the manuals from most of their machines. also Sewvacdirect has got the bobbins to go in it. If you go to the resources section I am sure they have more places to get parts and more shuttles. Wish I was more help.
