Thank you everyone for your help as always, I'll try to get a look at it tomorrow and see if it lives up to the "mint condition label" and has been maintained as I can't get the person on the 'phone at the moment.
Andy - The thing that does worry me and the same with Fed's is how do I know if the shutter speed has been set in it's lifetime without the camera being wound on? Not too worried about the lack of meter as I have a nice Sekonic.
Hans - That's OK I get the same hic!! you got me in the right direction though
Tom - It's amazing what I found there as I use to have a Zenit EM and still have a Zenith 11. I've played with a Fed 4c? but agree the earlier ones look better. Hopefully I'll find out if it's been maintained tomorrow as I can't get the person on the 'phone at the moment.
