Hiya bma.,can I wish you and your family a very Merry Christmas and a Happy and Healthy 2015,you really are a Star of TNUK with your very accurate drawings of many tractor units,long may it continue mate!! What kind of motor is Santa using this year seeing as you have used all his reindeers on the BBQ this year!!! I think a nice re-built MK2 Atkinson Borderer with 205 ■■■■■■■ engine would do the job nicely,what do you think? Cheers Benkku Dennis.
