Thanks Scotty, think I fouled up my reply so here goes again. Attached (hopefully) photo shows the panel with mains input and capacitor removed for clarity. Mains input was between AZ ans A and the capacitor was between A ans Z (Z is the lower right hand terminal with the yellow wire attached- the Z is obscured in the photo !
I've had a look for your motor's connections and I have one which is close but not an exact match. It's close enough to work out what's going on, but the way the centrifugal switch is implemented muddies the water a little.
The winding colours in your motor appear to be consistent with Brooks standard wiring code:
Run winding - red and black pair.
Start winding - yellow and blue pair.
The brass strip from AZ is likely one end of the connection to the centrifugal switch, and the other side of the switch returns on terminal S.
I've enlarged the Brooks diagram and marked up how I think your motor is internally connected. If you have a multimeter, you should find you have continuity between AZ and S when at rest. If you haven't then the switch might be sick - not an uncommon fault by any means, and not hard to fix. Be gentle when dismantling the motor!
Reversing is as per the diagram - swap the yellow & blue cores.
Hope this helps.

Geronimo ! Worked a treat ! Checked out connections with multimeter and they fitted your circuit so I reversed the yellow and blue and off she went in reverse. Just a moments worry as a horrble rattling noise started, but that turned out to be a loose pulley on the drive shaft. Very many thanks Scotty and you too Bill your help has been really appreciated.

I am new in this forum. Although, I've been reading various posts from this forum for quite some time now and I give kudos to everyone that has contributed immensely for a job welldone.
Welcome to the forum. I'm glad you find it useful and interesting. Speaking personally, it is little notes of thanks like yours and that from David above which make it all worthwhile. So thank you for your kind words.

That was a good thread.
Slightly off topic but some motors such as small shaded pole without means of swapping the start winding can be reversed by taking off the end bells and swapping them around i.e. poking the shaft out the opposite end of the windings.
