right for it looks like a 31 of some type. at 75 go buy it now do not wait.
Butt it is not a treadle. never go by the stand. at first visual on these look at the placement of the belt holes in the top. Those are towards the rear = elec. one hole forward and one at the rear or a long slot maybe be treadle. next check for the flywheel , I don't see a flywheel mounted. No a home type treadle flywheel will not fit, There mounting is about a 1/2 inch to narrow.. chances of ever geeting an industrial treadle flywheel well good luck on that. find me two.
still I'd be jumping up and standing on there door step
