That post cant have been a master post. I'm currently helping out a little with a local master post which has been renovated and the charging lead from the swan generator plugs into a socket behind the black cap on the air shaft. It also contains an rf connector and a pneumatic connector for the antenna mast. The power from the generator then goes to a two way switch (on the far wall) which allows you to have one battery in use whilst the other one charges.

Thanks and no problem, i've attached some pictures below from the last open day

Is this still available expeatfarmer? We are renovating an ROC bunker and thsi would be great back in its original surroundings!!
