Well, its been fascinating to watch unfold. Thanks guys. The Avia, SIPA and evan's Griffon are all completely new to me. Even now I'm not finding much about them on the net. I think that with one11's silhouette, although slightly different to the photo, the general layout remains the same, which is what I was trying to locate. Aviation in 1946 was obviously very busy.
Walter, if I may ask, without revealing too many trade secrets, how in hell did you find the SIPA?! When you start posting images I feel they're going to be very "scary."
