I don't know this particular brand (badge) but it appears to be a copy of the 3/4 sized Singer 128. It's a long-bobbin machine and I would wonder how difficult it would be to find replacement shuttles/bobbins.
Long bobbins run out of thread pretty fast so they're not as practical for sewing as something with a bigger bobbin.
If you just love it and want it for your collection, that's one thing. If you're looking for a practical machine for all-around sewing or FMQ, I would hold out for a model 15 that's treadle-able. (One that's already treadled, or has a belted motor)
Have fun!
