Welcome Craig, from yet another 400 owner!Good luck with the rebuild, as you will probably have already seen there is plenty of help and advice available here.If blue is the original colour then the bike is an F, not an F2, but that's being pedantic!If it is a UK bike then I believe F2 frame numbers start at 1096242 if that helps.
You and your cans of worms Chris . TBH, I have just been informed by him indoors, well him out in the workshop actually, that there is no definitive cut off point and it could be either / or.............so, that's me told then !!!!!
