In most years, Hagen-Renaker produced a “spring line” and a “fall line” of products, with new pieces introduced and some old pieces discontinued in both the spring and fall seasons. New order forms were printed for each season.
The dates given for each entry are the first and last seasons the piece was in production. The initials S for Spring and F for Fall are used. For example, F1952-F1954 indicates that the piece was first produced in Fall of 1952, and last produced in Fall of 1954. Note that order forms after 2012 were not separated into Spring and Fall seasons.
All dates were verified from the HR order forms. In a few instances there was some uncertainty, and those cases are marked [?].
