Here is a very nice older 3 slot payphone for your wooden phone booth. It is the 191G made by western Electric in the 1950s.  All in black just like they were. The 191G is heavier cast steel.

It has the swing out coin chute. This one is in very decent shape as you can see from the pictures. Its much older than the ordinary 233G payphones you see a lot of. 

Has more value than the 233G also. This beauty has the nice original porcelain number ring along with   old original dial card. This phone works fully as a home phone. You can dial out and it has an internal ringer to signal calls.

When you drop in coins you get a different sound for each coin as the coins hit the gongs. You receive 2 working locks and keys. The vault door and receiver hook are black as they should be. The handset is the heavier F1 bakelite receiver. 

I just love these old payphones in black. The  yellow middle direction sign card really makes this a strikingly beautiful sight to see.
