Vintage Fire Alarm Break Glass Signal Station.   Acme Fire Alarm Company.  Made of Steel.   It's approximately 5 1/2 inches tall by 3 1/2  inches wide.  The glass is intact, and the plunger button works as it should.  It hasn't been tested, however it was working when removed from service at an old school many years ago.  Note:  A small piece of felt is taped to the glass to avoid damaging the glass while on display or shipment   Please see all photos and feel free to email me with any questions.

I ship only within the Continental USA (lower 48 States).

However, International shipping is available if the buyer goes thru the eBay Global Shipping Program.
