So what I learned from tons of hunting on inter web is this is rare heavy duty double spool with pedal and special plug. Super expensive at the time work horse of a sewing machine. But this where gets little crazy another company copied and bought the design and made exact replicas called footomatic 4300 which where not as good as Heavy duty Dressmaker 6900 made with solid good reliable parts but to common person it was same thing and destroyed the business bought out and remade in Taiwan or some place else.
This Dressmaker sewing machine model 6900 even has the number it’s no. 5786 not sure how many are around or if there are any but thought that was cool. Includes this new hard case didn’t come with the original or paper work or that would of been so sweet but it still is tested working may need little tune up but motor passed inspection and it works like a champ and also has cool history to it. Well if your interested need more pictures or have more info for me that be great.
