Incompatible 'Trivia' items

With italics instead of links for film titles:

The second "Trivia" note reads: "Due to a clerical oversight, The Mummy's Hand (1940) was never legally made available for television viewings, and remained largely unseen until Universal Studios['] VHS release in 1997. It was also the lone mummy feature that Realart did not own the theatrical rights to issue in the late 40's-early 50's. Viewers who attended screenings of its sequel, The Mummy's Tomb (1942), did get to see about 15 minutes of footage cribbed from this film"

The fifth (and at this writing, final) one: "Part of the original SHOCK THEATER package of 52 Universal titles released to television in 1957, followed a year later with SON OF SHOCK, which added 21 more features."

Obviously, these are absolutely incompatible and one must be wrong. As the latter is appended ver batim to many of these vintage Universal horror pictures, one might assume that it was posted here virtually on automatic. However, the other is quite problematic. The "15 minutes of footage cribbed from this film" seen in the first sequel is mostly lifted from The Mummy (1932), with more-or-less close-ups of Tom Tyler and/or tanna leaves in place of similar shots of Boris Karloff and/or the Scroll of Thoth (instructions for resurrecting the dead). The total running time of footage in this sequence actually shot for ...Hand is almost certainly less than half of it, but this is somewhat picky. More significantly, I myself definitely saw ...Hand on US television, a local station in Denver, Colorado (specifically KWGN-TV, channel 2, owned by the Tribune company), in the 1970s, and I believe again in the 1980s on a basic cable channel (TBS?). This is highly consistent with the SHOCK THEATER release claim, and certainly incompatible with "...never legally made available for television viewings...." Can somebody come up with a verified list of the SHOCK titles to settle this once and for all? Please!
