Thankyou JasonB … I was aware of young Kennedy's building efforts as a fellow member of OMES 
Was interested in that Auckland model on TradeMe which is now listed for the third time but for the same reason he is selling I now think it is unwise to bid myself … mainly the problems of moving it between my two workshops … downstairs one becuase the Mill at 55kg was too heavy for me to carry upstairs … I used my handybilly to lift it off the floor from its delivery case onto its bench… but that was not an option to go upstairs.
I guess I will have to stay with my Gauge One/"LGB" efforts though I do have a 3.5" loco at about the same stage of progress with copper waiting for boiler …I must remember I am getting on in my 84th year 
Thanks everybody.
