[The Philpott]

Z repair successful. Drill bit fragment made over-length then clamped in mole grips and ground to around 4.5mm long with dremel and goggles. Damage probably originates because the scale plate clips one of the bobbins as it goes in and may have been forced in rather than slid in at a slight angle.

K=1/K=2/Amps work, Ohms not tried yet. Zeroing of needle somewhat improved possibly following attention to tightness of jewels. Some Intermittency in function remains and by a process of elimination this problem lies within the actual moving coil. We tried.

I can't think of another minor that shares this particular movement.. (1.25mA..?)
