I've come rather late to this posting but:
I have a G&S Conference microscope. It's a hernia job to move as it has a generous 100W built in power supply. I also have a G&S inverted microscope (that's equally heavy). More to the point, I have some G&S literature that a member of the Quekette (spelling) Society was kind enough to provide. It's a while since I looked at it but I think it's advertising literature. I can send you a copy.
regards
Graham
