Singer 176-11 - Antique Fur/Sewing Machine 1930s period. I don't believe it is pre-1930 but the listing didn't give me a choice so I'm noting it here.
This came from the iconic Bifano fur store that is no longer in business. It's a really special piece of art but its history truly makes it a conservation piece for the mantel. It really is a rare super unique find! Google Sammy Bifano or Bofano Fur if you want to learn more.
My husband is a contractor and helped close down the last Bifano fur store and in return he was given a few things from the store. I know absolutely nothing about this machinery or line of work so I can't answer any questions aside from taking more photos or providing more info that is visible on the machine. Either way though, feel free to ask me anything.
