This bike was donated to our charity and we would like to know just what it is. I already know it's a bit of a mixed breed. The decals say Supergoose but I have been told that it has had the decal added and is really another model. There are no frame gussets as you can see in the photos. I've gotten as far as to know it is probably an early 80s frame, but which model?

As usual, your help is appreciated.
