Found Oct.2010 on Brokstedt (north Germany) Swapmeet. You can still see the Alien Gas Tank mounts. That were the first things I cut off.
Complete Military TRW Front-end from UK
18" QD rear wheel with 19mm axle, 8" Tiger front brake from an Tiger 110 with 19" rim that I bought together with my Speed-Twin project and Honda CB400 handle bar.
Test fit with Wassell Banana Tank
Still on the hunt for more parts like footpegs, Brake pedal, friction Damper ans so on......
