Hello, Geoff-H,
Did you ever find out what happened to the other AK4-Kolibri is Australia?
I'm now in possession of the one in your photo & it's currently undergoing a rebuild to flying condition. The hail damaged wings where repaired & recovered in Sydney. A new engine has been ordered & I'm currently waiting for it to arrive. The cockpit canopy need outright replacement & it needs lots of bolts replaced & a solid going over. Parts are already on their way & Graeme (the seller) provided me with a fair few things to help with the rebuild. It's now in Brisane,
Regards Jeremy W.
