Yes, I had never lifted a metal tube before and I was startled at how much lighter it is than the glass counterpart.
I might be able to get that article through an inter-library loan (to make a better scan) if I can tell them the desired issue. As I read the first page, it is Sylvania News Technical Section, Summer-Fall 1965, volume 12, no. 2.
