Ive got 6 of the old ones here and they are all plastic lenses in grey plastic. I dont think they were ever glass, but I could be wrong.

Often when I've checked 'common' SAK knowledge it turns out to be incorrect. I'm not saying it is in this case, but it certainly seems to be worth checking now based on Syph007's report.
Does anyone have an old glass magnifier part they would like to part with? E-mail me and let me know what you want for it. Prof. gadget
