NOTES
Link to period advertisment [97K]Another of those miniature 'scopes aimed at radio and television servicing work, where portability is is of far more importance than calibration accuracy.

The servicability of this scope is particularly poor, with access to some items (including valves) being almost impossible. It may a miniature scope but that doesn't mean it can't have good access, as you'd get with the miniature scopes of Cossor, Metropolitan Vickers and even GEC.
SERVICE DATA Nope :-(
CURRENT STATE Some of the lettering on the front panel seems to be wearing off, despite the panel looking like the lettering is engraved ! The CRT has also had a bad day, the screen's phosphor burns looking much worse than the above photo would suggest.
WHERE FOUND Another donation from Allan.

Can you spot three valves ? More to the question, do
you think you could actually get at one of them ?
  Nope, turning the scope the other way round
won't help you ! Can you now spot the other two ?
I must admit I nearly missed these two. EMI servicability : Nil points.
