I checked what I got on this rather obscure Bücker type which was overshadowed by its side-by-side development, the Bü 181. I don't think many were built. Those I have found in the German civil register are
V-1 D-ELIO WNr 2101 also stated as Model A
V-2 D-EPCS WNr 2102 dito
V-3 D-EBRQ WNr 2103 dito
D-ENVQ WNr 2104 model A to OK-SHA or OK-SHO
D-ESBS model A
D-ECGK model B
D-EDEF model B
D-EDFH model B
D-EQLD model B
D-ESJF model B
D-ETFS WNr 2110 model B
D-EVGR model B
Maybe the A model had an open cockpit and model B the enclosed one?
Nahh, that would be too simple wouldn't it...
Anyone got any more??
Cheers
