Wow, thanks for the links - a wealth of information there and the answer actually lies in the MD12 manual and appears never to have been updated in the MD11 manauls - FMs after 3000000 did not have the manual change over finger guard - it was done electronically in the camera as from the introduction of the MD12.

There are no caps on the bottom of the FM so the MD11 screws straight on and just needs the power turned on - it also powers the camera's exposure meter. 

Now all I have to do is go out and use it!!
