My Stormbringer boxed set -- yes, I'm going to be talking about it a lot this week -- included a Chaosium Games Summer 1982 catalog. Except for reminding me that, yes, even Chaosium used to publish wargames, it's actually not all that interesting. There is, however, a mention of an RPG that never came to pass, with a supposed release date of Fall 1982. Call Reckless Adventure, it's described as "A role-playing game where the players explore the pulp adventures of the 1930s. It will include a sourcebook for the era, referees handbook, and many scenarios."
If Call of Cthulhu hadn't already been released by this point, I might suspect that this project was eventually folded into that game, whose original boxed set did include a 1920s sourcebook. However, it was scheduled to appear after CoC had already debuted, so I'm not quite sure what to make of it. Intriguingly, the perpetually-delayed Pulp Cthulhu is subtitled "Reckless Adventures in the 1930s," so who knows?
