there are as of today 26 interviews, of an assortment of stuff OFF Griders and GT people might want to use..
I ended up there when I read that they had interviewed \robin about the B 17 Inverter......
the 2015 interview with Mario is not verrrrry good too much background noise to allow older ears to hear clearly...
