The Stereo Realist, got one of the early models (first 1,000) from a friend (his parents estate) and I guess it had been in storage for decades
The leather case is not in the best shape but the camera is OK.
It is heavy! the camera feels like and old Ford; solid, heavy, but comfortable and reliable. The built in lens cover is handy helps keep it clean
Glass is clean, and shutter fires at all speeds.
By S/N this must be from 1948/9 which is also reinforced by the lenses marked as ILEX-Paragon which was replaced by David White soon after
Stereo Realist
The RF was out of alignment and after removing the bottom leatherette there were 4 screws (there should be 5) to remove and get access to the RF mechanism

Film is loaded after removing the back, trimming it like a Leica (20 sprockets)

Later models have a white dot, mine doesn;t, I used a bit of gold paint to mark the spot.
