Evening Graeme,
Coffee break, looks pretty quiet mate
I wonder If I forgot anything?
If the answer is no, then it looks something like the Darmstadt D-22 (but it's not it I suspect)
If it's yes and you mean the interplane struts, then it looks like a cabin type biplane by the depth of the fuselage behind the upper wing (which is wrong for the D.22)
Back to work now catchya later
