Rebuilding the head

There's always something that needs to be done, and here was today's challenge: rebuilding the head. Here the beast sits before I yanked it out of its moorings and took it to the cockpit for a rebuild. I can now field strip a Groko Model K-H head blindfolded during an artillery barrage. The instructions (here being studied in close detail by me) consist only of an exploded parts diagram, printed in microscopic print and very little detail. Hmmm... must be British.
