Anyone ever noticed these things are not waterproof by the wildest stretch of the imagination?
I have mine mounted horizontally on top of the Power Supply of my 19-Set Mk III. It in turn is mounted on a Carriers No. 23 'Breadboard'. The problem with this configuration, is the presence of the calibrator prevents the canvas cover from being securely fastened down to the carrier on the left side.
When I look at my Mk II 19-Set, mounted on a Carrier No. 21, with canvas cover, there is no way a calibrator can be mounted on that set and still have a functioning canvas cover.
A special canvas cover was developed for the Variometer. Does anyone know if a canvas cover, or storage case was ever produced for the crystal calibrator?
