I was "loaned" a 1052 when I was in college and it was built like a 
tank.  Much heavier than typical selectrics from what I could tell.

I built my own 48v drivers to run it and wrote  bunch of code (8080/z80) 
to run it as an ASCII terminal (yea, I know). Unfortunately, I've lost 
all of it in various moves/purges.
