Tomenosuke blaster build help

[Electronic Lids]

Hey all, I'm putting my Tomenosuke blaster back together after disassembling, weathering, applying steel barrel etc and am flummoxed. I'm not great at this and wondered if anyone had put together a how to, especially concerning the screws and that tiny spring that turns the chamber? The handle also ended up loose when I assembled...gah
Anyway any help in insanely appreciated. That or someone in northern Scotland I can pay to put it back together lol

Thanks guys
Col
