1850 Dollys in Essex ?

[Jummyboy123]

Hi, is there anyone located in Essex, Preferably Chelmsford area with an 1850, I need to check the cooling system I have put together is piped up correctly as I have replaced the expansion bottle with another with 2 feeds as i had a spare pipe, wasn't sure where it lead and none of the books or manuals have a detailed diagram of the layout so i assumed it was a double feed expansion bottle and stuck a custom one on in its place, the old one had somehow become lost.
