I dont have much really
i do have is a copy of my grandads log book (he has original) detailing every mission etc he flew during the war and time to target etc etc, its posted somewhere on this forum actually.....
I also have a flying jacket which has been handed down, not sure where its come from. I got it from my dad. It weighs a ton!! But damn its warm and comfy. Also have a flight manual for a hawker hurricane and a shell casing from a .505 round.
