I don't see how both these things can be true.I agree that there is no proof that Tractics was distributed on the day Lowry claimed it was (day 1 of Gen Con 4). However, Lowry claiming it on a copyright form represents some evidence that it was, and i think that it is also evidence that the other dates he gave were similar approximations of when the products went on sale, rather than arbitrary dates.
Nothing here engages with the points made upthread by @lowkey13 about industry practice. It is conjecture. The way to find out when Chainmail was first distributed is to actually find direct evidence (eg testimony of people as to when they bought it; sales receipts; advertisements; etc). Trying to infer from a copyright date, without any further evidence as to that particular person/firm's copyright dating practices, and in the face of evidence of industry practice that suggests the date is not reliable, does not seem very sensible to me.He may have remembered the day wrong for Chainmail, and his May 15 date could be an estimation. However, he did claim that date within just 7 months (his copyright form was notarized on Dec. 31, 1971). Therefore, while he may not have gotten the exact day right, he’d have to have been off by 2 months in his estimation to match the March date that many books claim.
Have you asked people like Peterson? I'm sure they will be able to tell you how they arrived at that date.Now let’s look at the flip side: what is the evidence of the March 1971 date that everyone has chosen to use? I know of no statement by Arneson, Gygax, or Perren supporting that date. While it appears in many books, none that I have seen offer a citation or explanation from where that date came from. From researching this, as best as I have been able to tell, that March date stems from the 2006 forum post I referenced earlier, which itself offers no citation or explanation.
No. The two bits of evidence known to me are your conjecture based on a copyright date, and the date given by Peterson and others. Given what I know of your methodology, and Peterson's methodology, I would trust Peterson's date more. If you can actually tell me why Peterson's date is wrong and his methodology flawed, I'm happy to hear it. But you haven't. As far as I can tell you don't even know how Peterson arrived at that date. You're simply conjecturing that he took it from a website.Now given that context, would you agree that the evidence for Chainmail being published in May, though far from a certainty, is still stronger than the known evidence that Chainmail was published in March?

From Guidon Games advertisement bit on Chainmail....
"This Illustrated booklet brings you comprehensive rules for wargaming with your medieval miniatures (such as the Airfix "Sheriff of Nottingham" and "Robin Hood" sets). These rules have been thoroughly playtested by the Lake Geneva Tactical Studies Association. They are designed for the serious table-top wargamer and combine realism and detail with the playability in just the right mixture.
Special features include rules for jousting and hand-to-hand combat and a large Fantasy supplement for gaming with super-heroes, wizards, trolls, hobbits and (why not) dragons, among others."

I wish. My DB#9 does not have a postmark; some were mailed in separate envelopes. It seems pretty random which were and which weren't.For the benefit of everyone here, could you please give us another data point and tell us the postmark date of your Domesday Book #9?
I think this is a great observation Zenopus.The April 1971 date of #10 on the Acaeum seems to be taken from the date of the one of the articles ("Ancients Society Report, Last Issue, 4/30/71"), which since this is at the very end of April might mean this issue was actually published later.
Rob, thanks for joining the discussion! I agree. I also think Zenopus is right that the April 1971 date given on the Acaeum website is likely earlier than it should be and ought to be corrected. @increment, to help Rob's, Zenopus's, and my research, could you please tell us the postmark date of your Domesday Book #10 (or any that you are aware of)?Here is the advert from DB #9. That issue was undated and thus has to be roughly ascertained by way of the issue preceding it (#8) or proceeding (#10)
