I think of all the cameras I have owned, or sold, it is more likely to be a JEwel than any other. Mine had a triple convertible lens mounted on a quick release plate.The length of her bellows extension would indicate a longer than normal lens.
I have a Trona 212 1/4 plate folder which is delightful, small with 3 plate holders in OE case
The whole kit is smaller than a Century Graphic

Better view of the Universal Juwel or Universal Palmos - it is the model with the 9x12cm format:

Maybe Jul is the short version of Juwel?
This is the ICA made for stereo (and you could use it also as a mono/panorama like in this picture); I think its predecessor made by Emil Wünsche was called the Reicka camera:
