I have not heard of a Scamp called an Acorn but whatever it is it is for sale if anyone is looking for a unit. Reasonable price and looks to be in decent shape.

An Acorn? Looks like an older Scamp. That's a new one on me too!
Scamps were built for a period year under Acorn name due to a dispute over the name. I think the Acorns are 1979 models.
