The One O Nine wth the BMW 801D is another mystery ship from Messerschmitt. Sure it was built and flew with discouraging performance. But no pictures are available. There are some pics of a radial engined 109. Burt I think they show the Bf 109 V21 with a Ptatt Whitney engine. A few plans exist:
What kit to use that's the question. As always I have some favorites: The Matchbox 109 E, The old Hasegawa FW 180 A an a quarterscale P 47 from Monogram.
