The first question is who made it and the second is for whom?
The resolution of the image is too low for me to read the plaque on the front but the arrestor is marked Bell.
If it were made for Bell, it would have a hook switch. Bell controlled patents that were applied for in 1877.
If it wasn't made for Bell, it might have used a non-gravity switch to avoid Bell's patents. What is the thing behind the receiver hook?

The second question is answered by the plate on top: MADE FOR THE AMERICAN BELL TELEPHONE CO.
The plate on front reads: SOLD BY THE So. NEW ENGLAND TELEPHONE CO. [and probably the city -- New Haven, Conn.?]
The knob behind the hook could control the switch. It would be interesting to see what's behind it inside.
Added is a closer view of the inside wires connected to the switch and a better picture of the front plate
Thanks for the photos Gary.
It looks like turning the knob completes the circuit by rotating the plate inside. Correct?
Yes, correct. To connect or disconnect the circuit.
I hope you bought it!!! This an early, extremely rare top box from New England Telephone. The lack of a switch most likely indicates that it was some sort of sound-powered arrangement.

It is a SNET box and a good one....Doug
This is a Southern New England Telephone Company sound-powered unit. These were a short-lived and unsuccessful experiment by the NET&T and SNET companies (and others?) during the 1883-1890 period to use up there left over parts once Western Electric took over manufacturing. These were a cheap alternative to a local or common battery and were used for point to point communications between something like a barn and a farmhouse, or a factory floor and main office. Most phones of this type are Viaduct with Post and Co., Chas Williams, or Viaduct magnetos and ringers. There is also a Gilliland example. These feature either a single receiver as both a receiver and transmitter, two receivers, or a receive mounted inside the door with a "Blake" hole in front. Most are stamped "WESTERN ELECTRIC COMPANY-CHICAGO NEW YORK" on the front despite having few, if any, WE parts. Some examples from New England have a shield escutcheon stamped "N.E.Tel&Tel Co, 1890".
