I just acquired an X-Ray head with integral transformer for use in a fusor supply. The assembly is in a tub of oil. Does anybody have an idea when manufacturers started switching from mineral oil to PCBs? I don't have a date of manufacture, but the assembly looks to be 40's or early 50's style, with grey hammertone finish.
