Not sure on overflights – no PR “fit”?
Corgi and the others do make some errors on colours, decals etc (had a dragon wings F-14 with spelling mistakes on the decals…) there is a nice 112 Squadron Vampire image complete with sharkmouth I found on the above link. Most models they make, especially of vintage and older planes you can generally find photo’s of if you dig – I’m stumped on a blue vampire FB-5 ! – The FB9 designation I got from an ad for the model thats with a large pinch of salt. Seems from the above it is an FB-5, but I’d love to know about the colour. I’m a bit fussy with my models, if its inaccurate I’ll sell it on!
