[Telecolor 3007]

The only telephone exchanges that coul do only pulse where the analogical one. I can't belive are still using one since they where mechanical.
For a good D.T.M.F. telephone try an "Western Electric" 2500.
Today I went to and house and construction store (bricolage) and in the bin where they had "electronics waste". There where 2 telephone plug (non-R.J. 11), one still packed. I wanted to get the 2, but the dern "bodyguard" didn't let me. Oh, stupid people, they preffer waste. I have in my collection 3 pins plugs and sockets for telelphone... those things wehre so big and sturdy that you can swear they where made for an washing machine, not for an telephone. Oh, and if you knew the position of the socket you could plug the plug with eyes closed... rotate it and you found the right position.
