The description currently reads: "Because this set has not been found in
any catalogs of the era, it is believed to be a store exclusive, likely distributed
in the US."
The 093 was a USA promotional set from 1965-68. The colorful box version dates
to 1967-68. Two sources are known: Parade Magazine, September 29th, 1968 and
through P&G(in a plain box) sometime 1965-67. Other sources are possible. The
1965 date is definitive as the pamphlet that comes with the set has a form number
from 1965(B-2187), and it was created as a direct replacement of the promotional
702 Special Introductory Set (which also had 93 pieces, same models, etc.) which
was used from 1963-64. USA only.
