Thankyou for the replies. I am trying to get a copy of the book, but so far Amazon have taken 2 months and are not sure if they can deliver it. The colours that I have so far are Sheffield Pale Gold (similar to the Labatts beer cans) a blue slightly darker than Humbrol dark blue, and roundel red for the cheat line. There is a video clip on the Snowbirds site that shows a formation approach, and all have their airbrakes out - so I will include a working system on my model. I am looking for any photos especially to see if there was any markings on the aircraft i.e HOT EXHAUST or bang seat triangles etc. As far as I can see from the photos I have there were no markings, and this has been confirmed by other sources
