Kev, Sorry sir, I'm not going to be able to help ya on this one.
In all the years I worked for/with phone people, I never worked with ANY of the payphone folks. They were/are a separate department within the companies. I have a few payphones myself, and like you they do not have keys. I have tried for years to find keys for the things, but the ones who have them keep them pretty tight. Once in a while a set would show up on the Bay, but not all keys fit all locks. As far as I know, there is no "master" that will fit all. Each regional had their own sets. (it takes 2 keys for each phone) Makes finding one for your phone pretty difficult. I lucked out once and had our local phone folks open one for me, but he wouldn't give up the key. Perhaps others have had better luck. If your interested, I will post a couple of good links. May take some digging, but lots of people on there with way more knowledge than I.
Wiring shouldn't be an issue once you get the thing open, but remember, there is a reason that we don't use those things any longer. You may not be satisfied with quality now....
You should be able to find wiring prints here: Telephone Collectors

Glad your making the tour, wish I could be more help.

Handy, but way to busy for me. 








The metal base is extra heavy duty and looks to have had some type of drawer mounting at one point. I really like these tops and I picked this one up because of its thickness. Not wanting to remove all the history, I just lightly sanded, shellacked and then waxed the top. I have reoccurring dreams of building it into some kind of rolling drawer assembly someday. 













It is my "rat hole" where I keep seldom used machines and storage for "Project" machines. All are in my way. Some of the machines are awaiting parts and time, and some of the others are just waiting... The plan for this area was for WORKING machine storage, pull out what is needed, put back when done. Not doing too well making this work............ I keep telling my CFO I need a bigger barn.....
