Oh and something I noticed today that I had over-looked - I still have the 30mm outboard gun shaped doors on the bottom of the wing (although the fairings were flattened). Initially this annoyed me, until I remembered that the D-15 was planned to eventually have the same basic armament as the D-11 (20mm MG151/20 inboard, 30mm MK108 ouboard); so my explaination is that the 30mm style mounts and doors were installed so the weapons fairings could later be added, if required...
Pictures when more paint is on...
