I got back to this again today...I've been putting it off because I really wasn't looking forward to this job!
I punched out 12 1mm discs and then bent some PE control horns to make the pulleys for the aileron control cables... (shown here next to the end of a toothpick)

These were then fitted, along with unbent (I hope!) control horns and I am going to leave those overnight to ensure they are secure before a dab of paint and a start on threading them all to rig the things! One thing's certain, designers back then had NO sympathy for future model makers!
The ailerons on this aircraft were a little unusual as they had no upward movement! The pilot could deflect the upper ailerons downwards, and these, via cables and pulleys, would pull the lower ailerons down also. Rubber bungees attached to the lower ailerons would then return the whole setup back to the neutral position when control pressure (probably considerable) was released.

Thanks for looking in, time for a pint after that lot!
