just another jockey,
Just to clarify further and I am not trying to be a smart @rse honest.
Yes you are correct when you say TTTE only had Mk 101s as did TWCU when it first formed.
However 9 Sqn at Honington (before they moved to Bruggen) and the earlier Sqns at RAF Laarbruch also had Mk 101s. The first Mk 103s were first introduced to 20 Sqn (newly established at Laarbruch following disbandment of the Jags at Bruggen) and the formation of 31 Sqn at Bruggen ( I was posted onto the Sqn, after I left TTTE, to help form it back in 84 and it was a whole new ball game with respect to MECU and reheat curve setups etc.)
Finally, please do not tell a Rolls Royce person that that the Mk 101and the Mk 103 are basically the same engine or they won’t buy you any beers
