Ha Ha Spitfire ya got me.
I did have both running a few years ago , then tractionalised
the whole L/O.
But I like all R/W`s and missed having a few Diesals roaming around.
Hence the intrest in RS 1`s .
I have A Fair Banks Morse, RSD 5, GP9 and a few more S/W 1200 on a shelve all ready for reinlisting on the section.
