I dislike telephone lamps ,however, I do buy them if cheap and use them in my phone room as...lamps. I will rewire them if they are dangerous (original cord as the lamp cord, 110 thru the hookswitch ect.). I prefer a 3 way socket with a turn switch on the socket when I use them. I also use lighted payphone signs for lighting.

As far as the recent D1 w E1 I noticed it has a white house dial center.
