Picked up the machine and cabinet/stool today. First, the hand wheel is solid, not spoked, ruling out 15-88 and 15-89??? It came with a 15K88 manual and a 15-91 sewing manual- yes both. But I think it is a 15-90 because the motor that had been removed from it looked like the 15-90 and not a potted. No internal wiring. It seems that 15-90s did have the scroll face plates. Anyway, now to decide what to do with the machine. But the biggest, exciting part of this is the cabinet- No. 42 Art Deco dark with the 3 right side drawers and 1 left side drawer with the Bakelite inkwell jar intact. It is in great shape with just some wear where the tops fold inward. The stool's wood has been cleaned but along the front and back sides under the seat there seems to be some kind of textured covering. Guess more research before I go ripping it off. The seat definitely needs to be recovered. No tears but I think it will smell better. Will post pictures tomorrow when the lighting is better.
