Got it, Beemer. Thanks. I'm not sure about a font difference, but I do see what you mean about the rounded corners, and Roy pointed out the size (of the panel) difference and MR. X has been getting after it...
My thoughts, FWIW...
An 1162 and an 1163 are very close in size (OAL, beam width). And let's remember that they even share an opening size: 1-7/16"! Even though Deeter's 1162 is a Plomb-Proto DBE wrench with pebbled size panels and his 1163 is a Plomb-only DBE wrench with pebbled size panels, they both have a pebbled size panel with a forged-in "1-7/16" marking. There's no
physical reason the 1163 would warrant
that much of a larger pebbled size panel. The size of the pebbled size panels on Plomb-Proto and Proto-only DBE's increase as the wrenches get bigger, to maintain the same
proportional style consistency for the size of the pebbled size panel to the beam of the wrench. But that's not what's happening here I don't think.
A Plomb-Proto 1163 with pebbled size fields, as MR. X is asking for, would prove that.
But, conversely, so would a Plomb-only 1162 with pebbled size fields.
And taken to its logical conclusion, so would any two wrenches of the same size (1120 through 1164) from both Plomb-only and Plomb-Proto production runs.
So, who's got 'em?!
My money is on Plomb moving from the full-shank pebbled panel on Plomb-only wrenches in 1946 to the pebbled size panels on Proto-only wrenches in 1950 in two stages: Plomb-only with XL-sized pebbled size panels and then Plomb-Proto with much smaller size pebbled size panels.
