The ones I have were made by Baush & Lomb.
The bad news is; they are no longer made.
The good news is; lots were made for anaglyphic Kelsh (sp?) plotters. You
may be able to find some by calling around aerial photog/map makers. This
anaglyphic method was replaced about thirty years ago with shutters.

The very bad news is:
John Bercovitz, and some others on this list, ran some tests which showed
that certain screen phosphors (as I recall, green) were illuminated by a non
corresponding signal (I think it was red). You may not be able to get a good
anaglyphic reproduction off a monitor?!?
