The 65/Nippy steering column cover plate screws onto the floorplan near the pedals, and is specific to the model.
The pressing is the same basic shape as the one found on the earlier Ulster (below) but the angle is different, the pressing deeper and the upper rim longer.
Chris Gould created a wooden mould to re-create an Ulster one and by removing its angled base, the greater depth of the 65/Nippy one could be hammered out in a sheet of thin mild steel screwed down to the hardwood former.
This is the comparison of the results with the base to the mould in, and removed:
Still some cutting left to do, and remove the hole in centre of the pressing…
