I'd say most likely post war
I'll update with new pics so it doesn't drag on, since when I first saw this photo I suspected it might even have been faked. However, having found it under discussion on an internet forum I believe it to be genuine - although there was no useful info given in that discussion other than "I'd love one of those" &c.
So there'll probably be quite a few questions I can't answer, above describing what it looks like
