Blackberry,
That is either a V2 or a 27. My guess is a 27. The bobbin winder is up higher on the 127 lower on the 27.
It looks like it has the early manual top tension release, you have to push on the tab to release the tension to thread it. I'm not sure though as the camera angle isn't clear on that.
Your pics didn't fully load, they are huge and my machine choked on them. So, did the motor come on the machine? If so and there is a motor mount boss on the right side of the pillar straight down from the main shaft you can make it into a hand crank machine.
You'll need a spoked hand wheel too.
That's a nice machine. Congrats on getting it.
Joe
