A man, dazed from running into a temporal snag, appears in a radio factory, whereupon (before
returning to his own time) he makes a radio that’s actually a Twonky, which promptly gets
shipped to a Mr. Kerry Westerfield, who is initially quite confounded and amazed at
everything it does.
Because of the story’s opening, I’m convinced the Twonky is from
the future. The “temporal snag” that brought it to 1942 feels like an unexpected time
rift to me, although the route back to the future is an intentional journey via an
unexplained method.
