I heard that the supply of actions that Bert Whittaker & later Geoff Hart used to build their specials had been the disposed of left overs from the programme to strip down 4T's & then gauge them to see if suitable for the L42 conversion programme. Bodies that were not deemed suitable or which were supernumerary eventually finding their way into their hands. However, I must emphasise that I only heard this from one source (Geoff Hart) & have never seen it substantiated elsewhere. Certainly, in about 1992 I bought an old hessian sand bag from Geoff. Inside it were four 4T bodies, all with pads on. One was a Trials action & the other three were BSA Shirleys. That is when he told me the tale. Strangely Brown has a keen interest in these derivative rifles - Mick, can you shed any light on this story?
Apologies John - I forgot to mention this when I pm'ed you yesterday!
