[TR] FW: What the HEAD is it?

If the engine was reconditioned in the UK by Beans Industries who did all
the S-T and BL engine and transmission rebuilds since the dawn of time,
it'll probably be painted a very unimpressive shade of medium to dark blue -
if it hasn't since been repainted. Certainly the engine number will bear no
resemblance to the original number. That said, if the car was shipped to the
US for sale as a new car, the recon unit could well be of US recon origin.
There comes a point when shipping old major units cores back to the UK for
rebuilding and then return doesn't make too much economic sense. Where my
memory is now failing me is whether the very early Razor Edge Renowns had
the wet liner four unit? Grateful if someone can enlighten me because I've a
niggling feeling the early 1800cc cars used a pre-war block and a new (very
short term use) ohv head prior to the launch of Vanguard in 1948. That's why
the earliest Ferguson tractors built in Coventry used Continental engines
because the Vanguard unit wasn't ready for release in the car or tractor.

The Triumph RazorEdge Vanguard head that I have has the same numbers cast
under the thermostat extension.  It has 21 1 X cast on top next to the
intake valve springs for cylinders 3 and 4.  This engine was rebuilt by
Standard Triumph in 1958 and it has a dated brass plate attached over the
original engine number area on the block.  I think the RazorEdge is a 1947.
