That gun they have, I didn't realise that Stalker came with it as well and gave it to my mate for his seeker. Later on I realise that Stalker had one and so had to track one down for him. They are just as hard to find as the missiles.
I have a spare Talon as well, bit of paint chipping though. I can send you a pic if you want.
At the conclusion of this Talon project, I may have one or two repaired Predator guns as spares.
I already had to repair my Skyquake's launcher as the handle came broken.
What I did was cut a small piece from a round plastic coated twist tie (about the same size as the original handle) and super glue it into where the handle used to be. then I would coat it with more super glue to give it a 'rounder' and solid finish. After that I would paint over it with copper colored paint and that's it.
