Hello friends, I'm brand new here so I hope this is the correct place to ask this! I stumbled across a vintage machine on Facebook marketplace that I was considering buying. It's not in the best shape, but it does seem to run perfectly fine from the video the seller posted. A cursory Google search tells me it's similar to the Pfaff 130, but otherwise I cannot seem to find a thing about it. It's being sold for $50 which seems like a steal. Thoughts? I was hoping to buy a machine of a similar style/era since they're heavy duty, but I have no idea if it's actually any good. Anyone know what that strange doohickey, handle looking thing on it is?
