The 86 is Vietnam era, as well as the 22. 86 weighs 195 pounds w/o batteries and normally comes with a single 30 line patch panel. A second panel can be added to give a total of 60 lines. There are pictures in the internet of two or three of them tied together as divisional switchboards in Vietnam. The 22 was generally used at the company and battalion levels, with larger units stacking a second unit on top of the original one and putting in the extra five line packs in place of the operator pack - a total of 29 lines. I won an 86 at a GL auction a couple of years ago, four months later it was reclassified as demil "Q" and returned. That sucker was as brand new (rebuilt) - anyway that's life. Is the 22 in a metal or fiberglass case? Fiberglass was the latest (22A) variant. Make sure the battery case and the headphone is present and working on any 22 you look at. Replacement battery cases are unobtainium, and the headphone (operators equipment) is not easy to find (any of the three variants). Covers (top) are also scarce, especially if you are missing one and looking! Brooke Clarke has some good info on his PRC68 site (and I'm the Mike he refers to in the 22 writeup).
