Ah, OK. Mine was a petrol. Learn something new - haven't noticed it in the history books.
First diesel LR I drove was an SIII - no hand throttle.
Had a PTO winch on my 127" (V8 originally) - one person in driver's seat for winching.
I have seen the hand throttle for SIII, we did try to fit one to the IIa, but completely different.
