Larry,
I am sorry to say thta I never made contact with Frappe. But Maybe someone from the forum here can be in touch with him.
The other question regarding the 1939-40 events. I worry that I do nto have any articles regarding Germns from that period tha are unknown. but know quite few men, who knows about their Czechoslovakian opponents flying over the France in French planes
If you need help in this way, I can point you the right direction...
