Interesting. Recently I came across an old note – which appears to be part of another, now disappeared, record – headed “aircraft unidentified at the Musée de l’Armée Bruxelles 30/8/?”. I think that the date would have been in the late 1970s. The note continues:

2 x Dagling type primary gliders
2 x modern type gliders (probably Grunau Babies)
1 x modern sailplane
Fuselage of a Voisin biplane
2 x early monoplane fuselages
2 x Auster fuselages plus one part stripped Auster fuselage
5 x Stampe SV-4 fuselages
Airship gondola
Rigid hang glider

Can anyone make sense of this note and/or identify the “unidentified aircraft” that I appear to have noted at the museum in the late 1970s?
