I found this site while looking for information about my old HK 430, but thought I'd share a picture of a vintage laser I have in my collection of lasers from the Kennedy years. It's a completely original and fully operational 1962 Hughes Aircraft Company Model 200 pulsed ruby laser, made by the company that made the very first laser two years earlier. I believe this to be the world's oldest commercial and/or operational laser.
I realize this is off topic here, but lasers are only recently becomming consumer products themselves and there are few, if any, other laser collectors out there. I thought y'all might appreciate it! This is also posted over in the Vintage Electronics forum here.
