I don't have any great expertise on checking the providence of machines. Pretty much what I do is look for sources online. I don't have access to any secret documentation or anything. Usually I trust what I read. Unless it's a place known for egregious mistakes, like Wikipedia or Needlebar. So from what I've read 1891 was the year that the VS2 transitioned to the Model 27. This one just misses the cut of being a first year, and comes in as an 1892 machine.
