Roger,

I'm glad it's on your To Do list and when it moves to #1, would gladly
assist ($$$) if you would recip.

Three of us listees have met and are discussing VW fiber parts and how they
may be made/sold.

When I first learned/saw of one of these on a van in Cuba, I placed it on me
own To Do list.
