Thanks for the info Graeme,
I just found this on Fright Archive
1939 | 1- - 0817 | Flight Archive
Says it's the Clark Cabin Monoplane
Edit: Too late it seems, well done Ken

Not on Aerofiles it didn't; wasted some time there, but it did find it on the F Archive (another one word search)
Edit2: Strewth mate, NZ thread is so slooow: only added about 65 pages in 13 months
and we fret when there's not many about
