Hello Tim, thanks for the information.

I also worked at Burndepts Erith on the 439 series during the early 70's - we sometimes saw the SARBES heading for the water tank and being hosed off by the air line but we had no technical involvement as that was handled 'up the ramp'!

I am just trying to find out the life cycle of the 301 - was it from the late 50's until the 80's?

A diagram would be really nice - did the destroy them at the end of the product life as the MOD seem to have a habit of doing?

The battery connector has a 5 pin plug on it and the Pathe video shows around 30 cells being used. My thoughts are that this was a dual supply, for back up purposes?, and that there was a common earth plus 2 pins for each of the supplies?
If so, does that mean that they have a nominal working voltage og 16.5 volts?

Is the case hermetically sealed? - I would love to look inside but I do not want to damage the appearance!

Sorry to babble!!
