Thanks for the great post. I can free-view cross-eyed on either of my monitors, but just barely do parallel, and only on the one that displays them smallest. You really made my day since this is the first time I've tried free-viewing since getting the second cataract removed.

I also guessed Kodachrome based on the contrast and color saturation.

Glad the stereo (slide ) continues to draw interest.

There really is no "color error" in this slide. I strive to make the images on the monitor look as closely as possible to how they look in the Realist viewer using a halogen bulb. The halogen gives a whiter light than the older type flashlight bulb does, and produces a better overall spectrum. Among the members of my FB Vintage Stereo Slides group are people very experienced with Kodachrome and I've gotten no complaints yet! I use an Epson scanner, so even if I felt I needed to, it is not possible to change light sources, and I can always "filter" in post if needed.

However, I also continue to make film dupes of selected slides, totally analog on a Beseler Dual-Mode Slide Duplicator, and when the filtration is dialed in just right for Kodak EDupe film (I still have a core of it left), the dupes are all but identical to the originals. The Schneider APO copy lens doesn't hurt either. Again, I defer to people who have more experience than I do; one friend, who has been shooting slides since the 1950s, and whose collection includes the slide I posted here, kept asking when viewing my dupes, "And you're saying these are NOT the originals...?" My copy work, either digital or analog, is done to high standards---mine!

In 1954, Kodachrome was available only in "daylight" and "Type A," so, without additional information, it's anyone's guess as to what is used here. Of course, both clear and blue bulbs were available (I have a stash of the clear ones as seen in my new avatar), and companies did make filter sets for the dual-lensed stereo cameras. If one knew better the time of day a slide was exposed, and there was a clear view of a window, one might better determine such technical details by examining the quality of sunlight. But there would be so many variables as to make that merely a slightly more educated guess.

Producing stereo view cards with these digitized pairs is very easy with a freeware program called STEREO PHOTO MAKER http://stereo.jpn.org/eng/stphmkr/. There is even a template to produce the cards by placing the images precisely and allowing text, background colors, etc. In fact, I just had some printed up today. They look great!

I too get a great deal of enjoyment from stereo viewing, much more than I ever did when I was younger since there was about fifteen years between getting both eyes done where I had no depth perception!

The Green layer in the older Kodachrome is rather transparent to ultra violet light and since human eyes cannot see it, this causes no problem in projection, or viewing. However, with most color camera films, ultra violet light exposes the blue layer. Some digital cameras do the same. I'd suggest that you try a Wratten 2B filter over your light source, which usually reduces the green portions of the image shifting towards blue in the copy. (A skylight filter won't work. It is not sharp cutting enough.)
Thank you so much for sharing that tidbit. I did not know this and would never have figured it out myself.

I continue to be awed at the variety and quality of expertise here.
