Looks like Sean paid attention when he read the SAA publication
guidelines.

My 2-bits, if it's sold as or claims to be a 2 x 4, pint, or
whatever, say so - that has meaning related to the artifact; just
provide actual measurements as well because there may be variations
that also have meaning.  Incidently, I believe there have been at
least two "downsizes" of dimensional lumber, one in the vicinity of
WWII as has been noted, and another later on - unfortunately I
haven't found or researched the dates, but I think they must be tied
to the Uniform Building Code.  The change in general use of 10d and
20d nails to 16d and 8d nails in residential framing is also tied to
the first "downsize."
