A belated thankyou for your replies - I got back to the Bristol Scout today after being sidetracked restoring a Blenheim ( I wish I could concentrate on one model at a time !!). After consideration I think I'll use Humbrol 106. I've admitted before that I tresspass on this forum as I build R/C scale models but this is THE best place to discover informaton on colours, markings etc....hopefully I will be allowed to continue.......
