I think you may not need to worry about that. I have also just gotten a '30s or '40s Kenmore cabinet and that one has the 1 1/4" round hinges. Pictures of that one will come once I put the 1701 into there. And once I get bored of the delight of having a machine that lifts up when you open the cabinet. But good news, I was trying to find a good picture of the cabinet on Ebay and found the hinges you want listed as "White Rotary" hinges.
