I saw that on ebay and also found it interesting. I don't know what camera
they used for that particular viewer but some people have taken aprox.
12 perf wide slides with modified Olympus XA's (or was that the XA2?)

Michael Levine (from Australia) has on his web page some similar wide
format viewers (14 perf!), check out his web page at,
