I need to find a source for new plano-convex lenses of the 6" diameter size. I actually want to put them in my old Kliegl 3355 (or maybe it's 3555) instruments, since the step lenses aren't working out quite as well. Anyone know of a source for these? I don't need the lens tube, just the lens. I'm fairly certain that someone out there would sell these, as they're one of two parts on an ERS that is most likely to break (the lamp being second).
Thanks,
Dan
