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?
From what I can search it looks like a Brother Riviera 110 maybe?

Manual available here it looks like. Photo matches.
Although maybe a slightly different model. Yours looks more flat on the top and the top left thread guide is a little different.

This site claims to have a foot pedal for that model. I wonder if it would have the same connector if the machines look that similar. You never know.
