Re: 6-button card dialer: To Die For!

Re: 30 button phone: Cool! Thanks, Paul, for including that.
Can someone check me on this? I believe only ITT made 30 button phones, Western Electric only made 10s and 20s. Can anyone confirm that?
BTW, ITT also had wall versions of these. They consisted of the whole base turned 180 degrees, a different switch hook (cup style) and dial also reoriented, but key strip not reoriented. Stromberg-Carlson also made these in desk and wall versions, and they also had 6 button versions as well (but not ITT or WE).
