OK this one 52 71 0 19931 is defiantly a VC-160 Mark II from 1971,where as this one 52 74 0 31626 also a VC-160 Mark III from 1974.It must have been almost one of the last VC-160's.Well the one that I thought was the Mark I must have had the badge changed as it does have a mark I badge on the front.If you could take some pictures from the sides so I can see where the handles go on the bases.This could confirm or deign the correct engine numbers.
