I've used and repaired EG&G proton maggies in the past. I can't remember a lot from them other than that, as you indicated there wasn't a lot to them.
I think its best to figure out what you need, because putting a proton maggie in a box may be physically problematic. If you really think that's the way to go, you might want to pick up this Geometrics/EG&G unit on ebay: ebay item #380328909088 Frankly, I've seen people use a cheap TCM2 magnetic compass fairly successfully as a magnetometer, but they were mapping cables, etc. Also, a google of "eg&g magnetometer pdf" will pull up a few documents that may be of use.
