More NG slides, etc

Well the D&RGW slides arrived today. They are housed in individual aluminum-like holders inside a magazine that holds 36 slides. These are made for an ARGUS projector. I never saw this type of arrangement before. They look to be a pain to extract from the holders, so my question is this....can they be viewed on any other projectors without removing them from the mounts. These mounts are outside the regular slide mount.
Sure wish I had a device to put these in from of the video lens, it would be a lot easier.
Some neat shots of both the Silverton line(high line), and freight stuff around Navajo Canyon, and Cumbres.
Anyone have an Argus projector to loan me?
