[Marcel Hogenhuis]

Hello Jaap, hello Merlin

Thank you both for your encouraging replies, I will call you later Jaap.
Merlin: that was one of the explanations I thought of too, so any primary evidence supporting this (most likely) theory, would skip one of the few indications that Germans ever used the pre war Venlo landingstrip as a Feldflugplatz before they turned it into a large Fliegerhorst.

All the best, Marcel
