I love the weathered Hurricane, I'm jealous that you found a model of the Saab, and I'm very, very impressed with the 1/700 planes.
Yes, the SAAB ( J 21 ) is probably the Heller kit. You can still find it in the shops. Hannants for example. Nice kits, I especially liked the Hurricane.
You really made some wonderful models there! really jalous of the Ju 88 and Me109 combination. Always wanted to have that one. Great job! Did you know that the germans tried such a ring around the plane in picture "tankDSC09657.jpg" on the Ju 88 as well? They decided to take it off though, because it made the plane too heavy, too inmanouverable and too much wasting fuel.[/b]
I'm not sure about a ring around the Ju88, but I know about the BV138, BV139, He111, probably FW190 (?) and ... Wellington BJ
