Whatever you buy, don’t forget to secure it in the panel as well as possible!

In the RAAF, we lost so many aircraft clocks that us ‘Instrument Bashers’ eventually had to secure them with ‘shear-off head’ screws.

I did this job on our 2 Squadron Canberras – and those screws were a right b’d to get out when we had to remove the clocks for servicing!
