Hello all, I picked up what I believe to be a Singer No. 2 Standard Industrial Treadle Machine. I’ve only been able to find very limited info and images of these machines and would like any resources and info the great minds here may have. I can only see numbers on the throat plates at the moment which are 913216 and 917216. Any and all help would be greatly appreciated , thanksat best or I'm just not that adept at finding it. I cant locate any serial numbers other than the numbers on the underside of the throat plates. Any and all info as to this machine would be greatly appreciated
