I found a 1911 Sphinx Model 27 Treadle machine in a thrift store last weekend and was thrilled to bring to home with every intention on converting it to a hand crank.
Problem? It's the 27 with no motor boss

I was informed that the hand crank I would need was the wrap around one that was very rare and very expensive!
Does anyone have a suggestion on ANY hand crank that would work or where to find a wrap around cheaper?
I suppose I could consider treadling her again, but I have no room for (another) sewing table.
Thanks for any help available!
