Yes, this is a long bobbin zigzag machine. It's set up to easily use two needles, so that will be fun to try.
This is one of those machines that once I new it existed, was on my "must have" list. If I ever find a nicer one, I'll upgrade, but at least I've got one!
Here she is next to a Singer 15-90
The shuttle carrier
And bobbin winder (and damaged nameplate).
As to it being a White - that's just the nameplate.
It is cast J-C34 on the underside of the bed.
And the needle bar - notice the notches on both sides for two separate needles.
BTW - I'm sort of collecting White machines that aren't white. Besides the black, I've got a green and a blue so far.
