Hi Alex
Interesting website.
What is the idea of asking for money on there? I don`t get it.
Anyway, I had a look on your forum. Did you ever find out what that flame-damping ejector was fitted to? It is certainly aircraft, not a vehicle as someone suggested. The only place I have seen that design is on German Heinkels / Ju88s, but I agree it could easily be American origin.
