Looks like a normal clock to me with the hours in the centre and minutes on the outer scale, not an ‘elapsed time’ clock. Do not know what it was fitted to, but clocks of different makes are often interchangeable.
Regards.

It looks like a Sangamo Weston Frequency Meter off a Britannia to me.

It is an Airspeed Calibrator made by R.W. Munro, the base probably contains mercury. I used a newer one of these for many years of my working life, this was purchased in the 50’s, and I believe it is still in use. They are used obviously for calibrating ASIs, and also low pressure instruments and pressure switches. These were very accurate for their day, but something looks wrong with this one as the needle should be on the zero mark. The one we used had a fine chain drive and this was know to come adrift once in a while, and was get a job to replace it. I am guessing but the 42 in the serial number could be the date of manufacture.

Where I used to work we had quite a spell of this type of thing, until we published a joke ‘dictionary’ translating these phases into there real meaning, such as ‘at this moment in time’ = Now, and after we did this it stopped fairly quickly!

Afraid this was a long time ago, and cannot remember a lot more. The RADAR PPI was obviously EKCO, and I believe it was for Concorde. The a/c was chosen because of its low flying speed. There are photos on the net suggesting they were taken in 62 – 64, this cannot be right as I had not started work then. I think the conversion was in 65 -66. I do remember the tail wheel collapsing one lunch time when no one was on the a/c, and the company having trouble finding mechanics who had woodworking experience! If I recall any more I will put it here.
