Some time ago I bought a used Bohli mechanical variometer ( over 15 years
old ) for $ 400 from a certain Mr. Bill Daniels in " good condition " The
photo he did send me showed only the back (!) of the instrument. I received
the instrument DOA; poorly packed, broken glass, in other words useless. Be
carefull if you buy anything from this fellow gliderpilot from Centennial,
CO
