Hi Zizi,
I did some profiles of both Wespe 1 and 2 a while back, but not sure if the '1' is acurate, as I just modified the fuselage keeping
the wings etc similar to the '2'.
I found no references that suggested the wings would have been different, so concentrated on the fuselage as the main difference between them.
So the profiles of the Wespe 1 are purely speculative.
Hope it helps.
