I can't find a perfect match.
I like the LVG idea, but the tail doesn't look right to me!
I think it may be a Curtiss Jenny type as well, which might explain the British (They're probably Aussies!) looking fellows in the foto. The wings look like they are almost equal span.
There's not a very clear image of the tail. I do have an image of an un-equal wing spaned type with a tail that looks very similar to our foto.
HAPPY TRAILS, FOKKERJ
JN-6H might be a good match!
Nine JN-2's had equal span wings with ailerons, top and bottom.
Several other models did too!
