Remember seeing the old black telephone on the blog from the transmitter visit in 2011, there are two other telephones at the transmitter. The one pictured on the blog then is the 302 model which 1st came out in the late 30's and was in circulation through the 50's. I'm assuming it was the original telephone at the transmitter. Barry McCorkindale took it home with him a couple of years ago when he was out at the transmitter.
The other two telephones are still there one is the rotary dial phone we are most familiar with which is the 500 model. I'm guessing it was added sometime in the 60's. The telephone was modernized sometime in the 80's with a touch tone telephone,I believe the color of the touch tone is ivory. Telephone service was shut off at the transmitter building due to leases still be paid on those phones around the middle to late 90's.
The black one sits in the workshop area while the ivory one sits to the right on a shelf as you walk in the building on the top level.
