Green Hornet Case Files coming out from Moonstone

Do you really believe that an appearance on the Superman radio series is relevant to our discussion of the Batman comics? ("Phony Song Publishing Racket"? sounds a lot like a Green Hornet radio episode that I have, and the title fits the "...Racket" structure often used there.) Similarly, the JSA/All Star Comics story is irrelevant; it's like citing what was going on in Justice League of America, World's Finest and Brave and the Bold to claim that Batman wasn't depicted dark and grim in the 1970s. This is especially so if the deduction of Roy Thomas and the late Jerry Bails that it was originally written to be the Atom himself is true; this was outlined by Thomas in his book The All Star Companion, and cited evidence included a caption referring to Batman by a nickname far more applicable to Atom than he. What sounds like a cameo in a Superman story is hardly relevant either. The "Tweedles" story doesn't sound at all on the level of the pre-Schwartz material we're talking about. For the other few, I remind you of my prior statement, "These were rare."

I'd now like to go a bit OT and discuss a few other things you mentioned.

Time travel via Carter Nichols (the specific means long since changed from hypnosis to physical technology) was in fact another then-current aspect of the Bat-feature that Julie dropped abruptly in his 1964 revamp. I read something that implied that there was quite a gap between a handful of hypnosis-based stories with Nichols and his reappearance with the more familiar chair-devices in many stories, which were seen well into the 60s. I believe the eventual official position (pre-Crisis, of course) was that hypnosis was used on Earth 2 and tech on E 1. It's interesting to note just how many characters and such jettisoned by Schwartz continued to appear in Batman stories produced outside his office. The only thing he actually had specifically written out was Alfred, and the TV show forced his resurrection! Nichols & his time travel device, Batwoman, Bathound, Bat-Mite and even the Whirlybats (one-man helicopters) would be seen in the Superman/Batman team feature in World's Finest and to a much lesser extent in JLA, and then given greater revival in the 70s by writers who had been fans.

Your statements about Atlantis are particularly interesting. Didn't know there was an Atlantis in Superman's stories until Lori Lemaris arrived in the 50s. I felt that the Wonder Woman Atlantis (firmly established as that of Earth 2 in the 1976 JLA/JSA crossover) was completely incompatible with the sunken and abandoned ruins of the initial Aquaman origin and Roy Thomas was therefore wrong to put the Golden Age Aquaman on Earth 2 in his All Star Squadron series. This wasn't too problematical, since the character made only one or two brief appearances near the end there, while Roy lifted another character called Neptune Perkins out of (IIRC) the GA Hawkman feature as an Aquaman equivalent. (There were a lot of others equally indefensible and too prominent to be similarly ignored, but I won't go into that here.) However, when I pointed this out in an online discussion of that comic's continuity lapses elsewhere, I was told comments in that JLA/JSA story had stated that its Atlantis had recently resurfaced. With a seemingly full population? Everywhere I go, I find jerks who will say just about anything to stand by the position they've committed themselves to, regardless of the facts. Oh, I don't mean you; what you've said doesn't come across as that sort of desperate straw-grasping and I see it all as made in good faith. Caught that in proofreading, fortunately.

The GREEN HORNET Strikes Again!

There were two mystery villains, "Mr. X" and "Mr. Big." Detailed information about both, limiting each to a short-run story arc of about four consecutive episodes each (off the top of my head), was added to Wikipedia's GH article without source citations. Someone else later complained that this and more added at the same time were lifted verbatim from the recent GH book by Martin Grams, Jr., and Terry Salomonson. Certainly both villains can be found on episodes in my personal collection, as can a handful with unsavory private investigator Oliver Perry. His heart was in the right place, however, because he like most people in the Hornet's world believed the masked man to be a big-time criminal, and Perry was trying to bring him in. He became convinced of a connection between the Hornet and Reid, eventually that they were the same man. Perry once tracked through the maze of front companies to prove that Reid owned the "supposedly abandoned warehouse" but failed to connect it to the Hornet. The aforementioned Wikipedia info indirectly attributed to Grams and Salomonson also discussed Perry, and claimed that in his last few episodes he turned genuine criminal. That's three more-or-less recurring foes that I know of, and with so many episodes not available (I seriously doubt as537's claim that there are "close to 700 or more" out there), there might be one or two others.
Speaking of that poster, I must suggest an alternate interpretation to his, "...one site that has over 250 downloadable shows [which Jerry Haendiges's site] doesn't even mention." Haendiges lists some episodes by titles that are not the ones read on the air by the announcer/narrator, because he saw his on some script draft (he told me this in an exchange of emails in early '07). Barring direct evidence that one way or another the narrator said on air a title he was not supposed to, we have to assume that he was reading the final selected title (when I included this reasoning in one email to Jerry, his reply completely ignored that part of it). Furthermore, many episodes do not have an on-air title at all and are issued by different companies under different titles. For example, what Haendiges and Radio Spirits both call "Man Wanted For What?" has also been available as "Amnesia Witness." I'd be very surprised if these two titling factors don't reduce that "250" number significantly.
