Original Boxes (for 5983-1) were produced in two styles, an older style (where
end flaps were glued) and a newer style (end flaps have corners notched and flap
sealed with adhesive seals). The two styles will cause a subtle difference in
the weight of the OB.
Old style has production number embossed into end flap, new style has production
number printed on one of the seals.
