Help Old Westfalia

Hi All,

Hoping someone may be able to help. I've just bought a 1960 Westfalia caravan. We love it, and can't wait to get out in her "Audrey". We are first time caravaners, it has a gas only fridge, and a gas heater. The fridge is a Sibir, the heater an Atlas.

We have no instructions and can not see what pressure these should run at? She is a German van. 

Does anyone have any information on these old vans. I would love to keep her as original as possible, but do have a little one so safety isparamount.

Thanks

Jase
