Vintage Bell System? by Northern Electric 3 Slot Rotary Payphone 233G? GREEN

Description

Vintage Bell System by Northern Electric 3 Slot Rotary Payphone 233G? GREEN. Working condition unknown. The bolts are missing that hold the main body on (that's why I was able to take pics of the internals). It's missing a knockout and has obvious scratches, chips, blemishes, etc. Rotary rotates properly. No apparent damage that would effect its usability...but I'm no phone expert. I can't find a brand or model number on it. Maybe you can tell me where to look? The handle on the ear piece says Northern Electric.
