Looks like a contact frame for doing a test strip either in 0.3 log progression i.e. 2,4 8 16 or possibly 0.15 log.
Will be interested in views form other ancient photographers who used these things back in the days when we had darkrooms.

Comments
These were called Actinometers, as Jack says for making test strips. They were used for 'sun printing' or in the darkroom.
