Steve is in Quebec, Canada.
I'm pretty sure there are quite a lot of people in WI that know him well. Here are the websites for the four NAVHDA chapters in WI (I don't know where you are located):
Wisconsin (West Bend) -
www.kmnavhda.com Area code - 414
Wisconsin (WI Rapids) -
www.ncwnavhda.com Area code - 715
Wisconsin (East Shore of Lake Michigan) -
www.winavhda.com Area code - 920
Wisconsin (Madison) -
www.wrcnavhda.com Area code - 608
Hopefully one of these will be close to you. It should be a good source of info on the Griffon.
Good luck.
