Some great anecdotes here! Being sadly long in the tooth, I did and perhaps still do have a 1960s or early 70s first edition, one of a batch of I think 500 self produced by the Calhamer deity himself. A topographical board and very stylish wooden pieces, painted white for the Russians, black for Germans, red for Austrians, green for Italians, French light blue, the Brits being a nice shade of navy blue. I imported it here to the UK from the USA and still remember the thrill of opening the package. Had a number of plays (and acquired a number of later versions as siblings, none of which match up to the original) until all being assigned during a house re-org to the back of the attic, where hopefully they still lie. I imagine the first edition may be worth something now, though I would be most reluctant to part with it. Yes, certainly brings back memories, from the early days of wargaming involving giants like Calhamer and Featherstone.
