The Cordon gas cylinder gauge.

Whilst working on the GWR Tool Van, I noticed the remains of a gauge fixed to the mainframe.

The gauge recorded the gas pressure in the cordon cylinder that contained the gas for lighting the interior of the van.

Somehow it had remained on the vehicle and deserved  a  bit of a refurb, the face was cleaned revealing the PSF graduations a new needle made, bezel repaired and a new glass cut.

Now mounted back on the vehicle,it can now be appreciated.for what it represents.
