Ship telephone or? ??? Edit: more photos added.
I'd guess railway. Originally.
Maybe an elevator phone ?
D/P
Looking at the hefty handset, I would guess to say ship phone. Only because I've seen ship phones with very rugged handsets.
I have added more photos on the top, and here 2 more and a diagram I made.

Screenshots from above link.
Many telephones used aboard ships are sound powered.
WOW! nice antique!
If you know someone who actually needs it to project I may let it go to good home, here it will just be stored in the basement.
