My guess is that the Trans came from a TR4A. Numbers for the TR4 were
somewhere around 49,100... It might be interesting to compare your
flywheel clutch/pressure plate assy. to an original TR3 set up.
The TR4A had a different clutch/pressure plate that required moving
the locating pin on the flywheel. The TR3 and early TR4 Clutch
assy were the same. Your a TR4 Tranny on a TR3 is not uncommon a mod.
It's advantageous to have synchro on all gears... Of course it
might be that it was the only Triumph tranny at the knackers when
some DPO needed a quick fix.
BTW, as an interesting asside here, my TR4 had a TR3 trans in it when
I bought it. The engine number frame were close eneough to be
original. The tranny was way off... The DPO strikes! Other non
original equipment included a later head, and non-standard Stromberg
Zenith carbs...
