Larsen built by Henrik Thor Larsen 1957-1960?
Thanks, but I can't confirm or deny that because I haven't been able to find out.
Allemano has half-answered the question posed by identifying where it was made, and the only other thing I know it what it was based on, so that would suffice for the other half of the question.
If you can give me some proof of the Larsen connection that might secure it for you?
