Hmm, again, this seems to point to the Patrol being a later Idea, which combined with Darryl's above add, supports his theory that it instead simply was discontinued, and then later the name revived.
Overall, an interesting find...
When my mowers were stolen earlier this year, three I had separated were missed, My fathers VC-160, my N.O.S VC-160, and my Lawn Cub, I think it is time to have a good look inside it's engine!
