I've been buying kits for donkey's years and have acquired a number of Tornados from the following:
Airfix, Italeri, ESCI, Monogram, Hasegawa, Revell (all IDS/ECM/GR.1) plus Airfix and Revell F.3's.
My intention is to build them all for comparison purposes, not commentating on accuracy, but I have noticed that the earlier kits from Airfix, Italeri and ESCI all have dual control cockpits.
As I intend to build all OOTB, us there any way to identify by serial number, which RAF aircraft were twin stickers? I understand that a total of 17 were built for all 3 participating nations.
