Hi Mike,
really good work about the cover of the filler cap and the sanding off of a fake cover in the mould.
Now you need only to add holes for wires that running from cockpit to aileron, behind the pilot.
Maybe you already know, the holes in front of the pilots were cellon covered to improve light on the little dashboard.
Enjoy your holyday time!

This is a bad photo of my 1/72 version from Pegasus kit:

Hi Roberto,
That's a very nice model, especially in 1:72 scale.
I've already drilled the holes in the rear decking for the aileron control lines.
Thanks for confirming the covering for the two ports in the front decking.
I assumed they were as otherwise water would have splashed over the bow and into the cockpit, something this aircraft suffered from, especially when flown by the Swedish (choppy water).
I guess these ports were to allow daylight in to help illuminate the instrument panel, similar to what was done on the earlier Aviatik 'Berg' D.1, which had very high cockpit decking at each side.
I'll try to relax in 30 degrees of sun in Mexico

Mike
