Buy these Fixtures in Belgium. They have hanged in an old garage. I think they are build in 1952 because somebody put a date and a signature on all ballasts. There are some rings missing that make it waterproof so hopefully I can do 3D printing by a company in Holland for not to many many to make it complete. Somebody paint the future gray I think, because I see some lighter gray colour under rad where the paint is gone.
The fixture is made from aluminium and the pipes to the box on the top is metal.
Also there ware 2 gold endcap Philips lights in it in total and one Sylvania black endcaps 40W. The other tubes were Philips 40W crimped and normal endcaps.
