I am trying to get the specs for the following Switchgear made around 1952 -1953. I am trying to get the oil content of this particular gear.

Doing an internet search comes up with this for support for that brand from another forum

"Long & Crawford became Areva, although your best bet would be refurbished switchgear suppliers (Winders, Slaters Electrical etc)."

and this search result

"You could also try EPDL in St Helens. This firm was started by experienced personnel from L&C and they continue to support the products."
