Newest addition to my laser stable is this Spindler & Hoyer ZL-150 stabilized He-Ne. Don't know much about them, but saw the "lock" light on the power supply and knew it was one of those, so I snatched it up despite it being newer technology. Don't have many European lasers and would love to find some. Ferranti, G&E Bradley, Siemens? Don't have the cables for this one but everything looks to be intact inside so it should work.
Found a good description of this laser here: http://books.google.com/books?id=b7U...0laser&f=false
