Rebuilding Metal Cone CRT's

[Duke Nukem]

There were some rectangular tubes with metal cones too, I don't know their numbers off hand.

I'd totally forgotten that there had ever been rectangular metal cone CRT's, but I now remember that RCA introduced one (the first?) towards the end of 1951 with a 14.5x11 inch screen area; but the UK were already starting to use all-glass CRT's not long after round metal cones appeared over here so never got to see a rectangular B&W metal cone. If anyone has a picture of one (particularly that first RCA one) I could shamelessly steal for my website it'd be much appreciated.

TTFN,
Jon
