Which Owners manual?

[Coppertop1234]

I have found 3 different owners manuals for the CB750 F1 and cannot identify which one for which bike, if anyone can clarify what was original issue please

The brown one was from the states


The Blue & Yellow ones from the UK





We have a 1977 F1 in Sulphur Yellow and a 1978 F1 in Candy Red

And this is my new  come out of retirement transport for the summer
