Does anyone know where i could find a roof top picture of a torpedo unit,that show`s the rear of the air tanks with the piping. I have the Diesel Era mag (may/june 2000) with the frisco GP35 drawings for these unit`s, but as yet i have`nt found a pic on the interweb. And also, i`ve found a pic of #709 dated 1976 in it`s original livery.Would this be the last unit painted so,and what date was it finally re-painted. I ask because i`ll use this as my modelling date. Thanks for any help on these question`s. Brian,UK.
