I have one! There are several designs all based on fairy tales..I also have the Hansel and Gretyl machine...they are chain stitch machines. It looks original to me...but not as old as mine..this one has painting in the corners, the oldest in the series do not..this is a pic of the H & G machine..

I am no where near an expert on these, but just from my shopping around I know that there were small differences in the designs of the characters over the years, but have no idea how to date them based on that.
This is Snow White and 7 dwarfs..I would love to have this one!
