William thanks for doing that . As i and a friend look at this thing we
cant see any way it could combine the 2 pictures so it must be ``magic``
..but i dont have any slides or whatever goes in it to try it .

There are some huge lenses in it and more lenses in the nose . It has 6
adjustements to move or focus the back , front & bulb so maybe it blots
out the wood divider on the slide holder somehow .

Let us know what you discover.
