[TR] FW: What the HEAD is it?

[Dave Hogye]

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.
