I now recall that some of the airframes resided on George Henry Flowers scrapyard in Chippenham, Wilts. I know they featured regularly in the local press, so there may be some images in the Gazette library.
Chippenham, Devizes and Wiltshire news, sport, classifieds and more from the Gazette and Herald
A message in the Gazette would probably unearth more pix.
I know that were a matter of fascination for the local ATC
There is also the German Spotters Group with some pix attached at
Spotting Group Gütersloh - Flugplatz von 1937 bis heute | No79SquadronSwift.
Finally there is a guy called Barry Flahey in Canada who took many aircraft pix in the late fifties at Gutersloh. I do have his contact address.
