This mailing list has aroused an interest I have had for many 
years. I have around 100 antique Holmes pictures, and have made 
some on my own. When travelling I have made color-slides of the 
type "Click, Lean, Click". Those have been viewed in a simple 
viewer.

Today the only beamsplitter I can aquire in Sweden is the Pentax, 
and the price on that is more than $250.

I think a beamsplitter could home-brewed. First-surface mirrors are 
quite easy to find. The drawings I have seen are of two types:
1. Similar to Pentax. Seems to be easy to build!? ;-)
Should the angle between the mirrors closest to the camera-lens 
be 90 or 100 or whatever?
2. I would prefer to have the negatives in the landscape format. 
Tri-Delta may be difficult to build, but in REEL 3-D NEWS October 
1980 (which I have) a beamsplitter (similar to ELMO ESM-1) 
containing 6 mirrors is described. Has anyone reproduced that?
3. I have two identical projectors. Should they be mounted on
top of each other? Any problem?
