[Milsurplus] ARC-2 Owners?

[w7fe]

I have recently acquired a very nice RT-91/ARC-2 Collins transceiver (yes, likely the very first Collins-produced transceiver, c. 1945 -- uses a 70E-1 PTO common to both TX and RX circuitry, 2-9 MC, 8-channel Autotune, CW/MCW/AM, pr. of 1625's modulated by pr.of 1625's) and would like to hear from other owners..  

I know that manuals are available from at least three sources on line, and I do have the W4WKM conversion article from October 1963 73 magazine. I'd sure like to find a copy of the booklet which is referred to in that article (contains schematics and four or five very useful-sounding mods, at least two of which look like they are already installed in my unit) as well sources of any other available knowledge on this beauty and/or suggestions of other active groups/lists to visit with this request?

Again, I'd really enjoy an opportunity to compare notes with others who are familiar with and perhaps still enjoying this rig. Anybody out there? .
