[TR] TR3A Manifold

I believe that is the wrong commission number range; TS13052E was the
introduction of the "high port" head.  But that manifold should work fine,
other than lacking the boss on the balance tube.  I'm not even certain it is
'wrong' for your car; it's the latest manifold listed in my TR3 SPC.

Also wrong description I believe.  According to my information it was fitted
to 100 engines starting at TS16801E, and then to all from CT21471E through
the end of TR4A production.
