"Related to Galileos. I've not seen one in a very long time and when I asked a hardware guy, he said he hadn't had a call for one in a long time. Doesn't mean there aren't some out there but they may be being serviced by platesetters.com."
"Parts: From us, it's on an "as available" basis. If we have one, we'll sell it. Once again, platesetters.com may be a better bet."
"Last, the chemistry. We [AGFA] still sell some violet plates in some environments. So chemistry for some violet plates is indeed available.
