Edwards Signaling 435-4E1 Adaptabel 4", 12VDC, 0.125 Amp, Gray Bell USA Untested

Description

ESTATE FIND
!
Purchased inside a box lot at an estate sale.  Appears to be in good condition from what I can tell, but I am a woman and have no idea how to test it.  :)  (Just a thought... The other items that were inside the estate sale box all worked, so there's a good chance this one will also, but I make no guarantees.)  Priced accordingly.
Wear consistent with age and use.  As usual, I am selling the item as I found it at the estate sale.  Untested, so I am selling it as is for parts or repair. Zoom in on all of the photos as part of the description.
See photos from all sides for more details, including one of me holding the item in order to give you a better idea of the size, etc.
Message me if you have any questions.
