Found this in warehouse, any thoughts on age, etc.

I am not a collector but the research I have tried find it interesting.

I could not find any markings so guessing there were alot of manufacturers but still like to check it out.

Got these pics but can take more detailed views if someone has suggestions.

No marking? That's gonna be hard.
