i have wanted one of these cameras for ages ... congratulations, you are one lucky person !

the thing that is hanging under the camera is a chemical tank,
you should also have a " sleeve " so you can stick your arm in the camera after the exposure
and drop your paper into the tank.
i am not sure what kind of developer was used, or if there is more than one tank ( dev+fix ) or if the developer
was a proprietary monobath the chicago ferrotype company had for their direct positive paper
you could probably use that to shoot paper negatives instead of what it was intended for . and drop all your exposed sheets
into the tank for "post exposure storage "

have fun !
