Off ebay:
Fujimi Spitfire FRXIVe lowback
Kora Fw Ta 152S
Kora Fw Ta 152H recon version
Kora Fw Ta 152B-5 attack fighter (new wing)
Kora Bf 109 G-12/AS
The Ta 152s are all the superb Aoshima kit with lots of new resin goodies. The 109 is the AZ kit. Czech markings for that one, I think. If it includes a spare canopy, it may be possible to copy some of the parts to upgrade the Revell G10 into a spare two seater.
2 x Pavla Avia S199 canopies - both Erla and the later blown type are included, the latter being the one I need.
