Todd,
Even though this was only a necessary byproduct of my analysis, your 3/46 advertising date for pebbled wrenches (DOE, DBE, Combination) helps confirm that catalogs #19-R REPRINT and FOURTH PRINTING were first published in wartime, and confirms (and refines) the way I date those catalogs in more detail than the 1942-1947 date range assigned to these catalogs by Van Natta, AA, and the Tools Archive (at the moment).
Note again that Catalog #19-R REPRINT includes the same illustration of the Utica-made adjustable wrench as the earlier #18-A, #19, and #19-A. And that Catalog #19-R FOURTH PRINTING includes the illustration of the J.P. Danielson-made adjustable wrench. This will play a role.
In November 1944, when Plomb was advertising only drive tools with pebbled handles, Plomb Catalog #19-R REPRINT – which I dated in my discussion and chart above to no earlier than February 1944 (one month after a January 1944 Price List found in Catalog #19-A) to October 1946 (a month before Plomb acquired J.P. Danielson), was also showing only drive tools with pebbled handles and included the Utica adjustable wrench illustration. We can move that October 1946 date back to at least March 1946 now, since Plomb was also advertising wrenches with pebbled fields by that date, and Plomb Catalog#19-R REPRINT shows wrenches without pebbled fields.
I date Plomb catalog #19-R FOURTH PRINTING to November 1946 (when Plomb acquired J.P. Danielson), to at least March 1948 (date of Price List included with it), because it includes an inserted page (63B) showing an illustration of a J.P. Danielson-made adjustable wrench instead of the old Utica illustration. Most of the rest of that catalog was first printed in wartime, because it includes WPB Limitation Order L-216 markings that were revoked by May 1945, and dates to no later than March 1946, because the drive tools are pebbled, but the wrenches are not.
Together with the wartime markings analysis, and the adjustable wrench analysis with your J.P. Danielson acquisition research, your advertising dates now help show in a little more detail how these catalogs were first published in wartime, then apparently re-used until the Proto/Plomb Catalog #4820 was copyrighted in 1948.
I’ll let you figure out how to handle that complexity in the Plomb sections and the catalog library on the Tools Archive.
The timeline (for first pebbled tools introduction) should be much easier to handle by tool category.
