Here is an original AT&T, Western Electric 2503 desk telephone that is still new in the box (NOS) and it fully works. These are starting to be very collectable. This one is the Gray color. There are not too many 2500 phones if any in gray. Very unique.
One great feature is the white plunger. When you lift up on the white plunger it becomes a voice canceller. The party on the other line can not hear anything going on in your room. When you push the white plunger back down they will once again hear you. This telephone is also for the hearing impaired.
You will be the first owner of this phone with its unique features and color.
