Singer193

I have my eye on a Singer 193 - guess I'll have to make a new thread, but I'll ask here also. It seems like a rare model. Possibly 193q (made in Mexico in 60s). No real info available online. It comes with a table, foot pedal, but seens foolish if I can't find any parts or info at all on this rare model.

Is it safe to assume that the more popular models (15 / 66, etc) parts will be interchangeable even though most are made in USA, etc. Or will I be stuck with a mexican model with no parts availability? It's available close to where I live and in seemigly good condition, but I want to use it and not retire it at the 1st breakdown.

Anyone know anything about these?

Thank you
