Long ago, brown (color suffix -54) was used for 500 sets and 54X and 56X series key sets. They MD'd them in the mid 1960's. They are too rare even to consider finding one.

WECO never made anything in ash.

So I need an ITT brown and an ITT ash.

Arthur,

Did ITT make a brown 6-button rotary set? I don't ever remember seeing it in brown. I have an ash and brown TT 6-button. Of course I worked for an interconnect in the mid to late 80's and rotary dial was not ordered very often. I will have to take a few snapshots of my WE 2565 collection. I have at least one in every color made and some colors I have two. 6-button wall and touch-a-matics also. This was all uninstalled from the house I grew up in and I packed it all very nicely in boxes. I even took out the KSU and some of the 25 pair cabling as I knew the new owners didn't want it.

ITT definitely made them in brown. We sold a bunch of them to government agencies in the 1980's.

Ditto. The Fed's specs were that they would accept either tone or
rotary - but they bought whatever was cheaper - and that was rotary, by about 15% if I remember correctly. In the early '70s we probably did 50/50 rotary/tone with a sizable minority of the sets being brown ITT 564s & 830s. By the late '70s though almost everything commercial around here was going tone.

Except the Federal Government jobs,

I installed a couple of thousand Stromberg - Carlson "mini call directors" (1800 series? I can't remember) - 6 button sets in Brown, Ash & Beige for the feds as late as the early '80s. The S-C set were nice - with all buttons in the up position you had an intercom path available. Almost like getting a 6th line "free".

Sorry to disappoint (this won't come as a surprise to most of you), but I just don't have the time or the organization to take on such a project. If anyone wants (if I still have the file) I can send what I had and that person may continue it on their own. I don't think I still have the file but I will check once I get home.

Now you see why it would be hard to find that book there is to much information and differences in the systems to be condensed into one book. Find the file and hang onto it you may need to do a paper for high school or college someday and that would make an interesting topic.

I don't think you'll do much better at it then the people at Bell did. Check this link:

I still have Volume 1 in hardcopy...not in very good condition, but it is still readable.
