Thanks, this helped me to refine my own notes on these labels. This is what I have learned so far from W.B.lbl in combination with M. Sherman & K. Nauck, "Note The Notes: An Illustrated History of the Columbia Record Label 1901-1958," page 9, https://www.friktech.com/labels/ColumbiaLabelography.pdf, and my own observations:
The original July 1941 release (LaurenceD's labels) shows a CBS label with "Trade Mark" under the CBS logo and three lines of patent text under COLUMBIA, listing patents 1625705 and RE 16588 (used September 1939-July 1941).
Bob's copy represents an August - December 1941 CBS label without needle promotion and with three lines of patent text under COLUMBIA, listing the patents 1625705 and 1702564.
Trainman's copy is from ca. 1943: CBS label with three lines of patent text under COLUMBIA, listing the patents 1625705 and 1702564 and the phrase "Use Columbia Needles" (used Jan. 1942-Oct. 1945); the inner pressing ring (ca, 1.14" diameter) shows up in 1943.
The "For perfect tone..." language first showed up in January 1942, hence {Images #1444450 & 1444451} without that blurb has been moved to before {Images #1005513 & 1005514} which do have it.
Label variant images added. "Trade Mark" is not above Columbia. Although difficult to see, the patent phrasing below Columbia appears to be different than on the original label images.
