The attached scans list all the F, FV, FVP and LS of which I am aware. There are clearly many hundreds more in existence.
As well as the impossible task of listing them all, the other main aim is to try to chronologically list the changes so as to determine what took place and at approximately what serial number.
I hope it is of some interest and use.
Please contribute to the data on the list if you have a relevant model or know the whereabouts of one. Please post information about your engine or send me a pm.
Thanks.
Jeremy
