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?
I think the machine you have is a Brother Super Flairmatic 190B sewing machine. (I used Google lens on the picture you posted). If you search this on Google, you’ll find quite a bit of information, and there’s even a YouTube video!!! You might even be able to find a manual this way. Good luck!!!
