Lot of 12 Vintage SH Couch 4 Unit Apartment Intercoms + 1 Single unit and Parts

Description

Lot of (10) Vintage SH Couch 4 Unit Apartment Intercoms plus A Single Unit and some Parts including:
Screws, what appears to be a diaphragm in an unopened (but torn) envelope, another unopened envelope, and some Stromberg Carlson Schematic Drawings. I am not sure if the drawings or envelopes are related, but these items were all found together and have been in storage for at least forty years. The condition varies on all of the units, so please inspect all of the pictures carefully. The single unit and one other have been painted. There are the expected paint flecks on the others. Some have a very nice patina and should clean up beautifully. Some have missing screws, one has a detached bell, some have missing or broken talk horns. Definitely enough parts to restore half of them, in my opinion. ONCE AGAIN PLEASE INSPECT ALL THE PICTURES, WHAT YOU SEE IS WHAT YOU GET. I have no way of testing these items, so they are being sold AS-IS. Feel free to email me any questions and I will do my best to answer. Thanks for looking.
UPDATE, just found two more (not pictured) 12 total units included in this lot. Both are unpainted, one is missing it's "talk horn" the other "talk horn" has very rough edges. Nice overall condition.
