PN, thanks for that; I'll try your RBL plot. Being of your vintage and as an aging member of SODCAT, widowered and with not a lot to do apart from e-mail the sons now flown the nest and walking faithful dog, I will now embark on this with relish. I'm not desperate for extra income so I pledge any advantage to the H4H fund (my no. 2 son currently at Bastion doing helio front seat stuff).
SP I totally agree; there are too many of the services highly paid ilk looking after their their own futures for those lower down the ladder to benefit.
ps, if anyone can guess the significance of my label, maybe the smilie will give a hint
