whinnytoo,
That machine is a badged machine made by WHITE. It turns opposite Singers and most others. Nuther words the hand wheel turns away from you. If you turn it towards you it won't pick up the thread right.
It's not really a "heavy duty" machine, just an old style heavy domestic one.
It uses standard 15x1 needles seated flat to the right, and threaded left to right.
It uses White / Kenmore narrow but bigger around bobbins. Once wound the bobbins hold as much as a class 15 bobbin does. When putting a full bobbin in the case put it in so when the case is threaded the bobbin rotates clockwise as you look at it and pull the thread.
They are excellent machines that do really nice stitches. You just gotta turn 'em the right direction.
And they do tend to develop flat spots on the motor drive wheel. So if you're lucky and it doesn't have a flat spot take a spring loaded clothes pin apart and put half of it between the motor and machine body. That will keep the drive rubber off the hand wheel and stop the flat spotting. I do that one mine, I hate the roar they make with bad drive wheels.
