up to you barry ! his information all looks impressive but the few cars i know much of , the Bruetsch , is severely compromised by his section referring to The Tourette where he appears to be way off the mark . admittedly period write up's appear unclear on this as well though .
i have now refound FREUNDESKREIS SPATZ VICTORIA with an email address which they did not have last time i was in touch with them - how time moves on . unfortunately Herr Hoegner the contact speaks no english , and i no german , but he used to show my letters to a friend who translated for him . i shall approach him again .
Thanks
