This is an interesting machine. When I first saw it, on the shelf in a thrift store, I thought it was a Singer 500 series machine. But it isn't. It's a Polish knock off, made in Poland in the 1990s and it has a curious history.
Once I had figured out that Finesse was the name of the line, not a model designation, I went looking for info on it. Couldn't find a darn thing about them. Then, I remembered Alex Askarov who lives in the UK and asked him if he knew anything about them. Turns out, he does. He tells me that the machine was made in many different models under license from Singer and sold well, world wide.
