Yup, and probably slightly later by Morgan.
Easy way to tell is the location of reverse gear - left and forward is LT-77, right and back (behind 5th) is R380...
And yes, the synchro on 2nd is weak - I had a 200Tdi Disco where synchro had failed, double declutching gave a faster change anyway...
I'd second the Ashcroft option...
Cheers,
