  Probably because it was on the Spitfires too.
  Parts sharing meant they could share the same surround on Spits, GT6s and Some TRs
  
  40 years on, with rust being what it is, it's a darn good job they did!

    Sorry, that doesn't answer the question as to why in that surely the GT6 and Spitfire share the same bulkhead?
    Is it the case that the TR4 shared the same windscreen frame? I think they have the same piece of glass, not sure about the frame itself though.
    The answer may lie in a remnant of the Herald body procurement saga of the late 50's, a lack of pressing facilities to press the bulkhead/screen panel in one piece. And bolting together is a viable alternative to welding separate pressings together, used elsewhere on these cars with chassis.

      The frame is identical (that is why they are so damn expensive, bloody TR parts!) except TR and early spitfire don't have drain channels. They of course don't rot as quick.

        When the TR4 came out most sports cars had bolted on windscreen frames. Most cars of all types also had bolted on door-window frames, where the frame is not part of the door pressing.
        
        The reason door frames were separate was to do with tooling cost, so I would guess that a larger press that can make part of the bulkhead at the correct angle to the rest of the panel, and do it consistently, would be less cost effective than making a separate bolt-on part.
        
        The GT6 frame uses the same pressing but does not have the rods that go down inside the bulkhead.
