Just a shot in the dark but I thought it’s worth trying:

I bought this old Brother machine, but it came without a foot pedal. The machine has a power cable and another cable with a 2-pin flat prong female connector, which is where the pedal is supposed to go.

It looks very similar to this machine on EBay: https://www.ebay.com/itm/283520681227?_ul=IN

All the “universal” pedals I see online don’t have this kind of connector. Does anyone know where I can find a replacement, or even what type of pedal I’m looking for?
