Although anyone with info is certainly invited to respond, this post is aimed primarily at Starship, because he seems to have a talent for unearthing info on these types of planes...
So Nick (or anyone else), can you post some pix and/or info on the following types of aircraft?
PZL Mielec M-15 Belphegor
Transavia PL-12 Airtruk
Lear Fan Model 2100
Pilatus Britten-Norman Trislander
EMBRAER EMB-121 Xingu II
Pilatus PC-6 Turbo Porter
