My colleague saw these nice M20 and G14 BSAs the other day when he was on his way home. As he knows my interest in WD motorcycles he took these pictures for me! Anybody we know?
Regarding the ex-Dutch Army V-twins: there seem to be at least 4-5 in the Netherlands/
Jacob de Groot is supposed to have one, the Dutch Army museum in Delft has two (one on exhibition, and one in storage in Grave), there is a civilianised one in Limburg, and near Eindhoven is one currently under restoration (meticiously).
So at Henk: start saving as Jacob seems to want to sell his? (but rumour has it is a pre-war one, and not ex Dutch Army)
The one near Eindhoven: when that came up for sale, I could not afford it. But it could have not have gone to a better home!
