Tree calipers did not appear in the 40th edition catalog of 1944; tree tapes are listed. It is listed in the 41st (1949) and 42nd (1954); it is re-numbered in the 43rd edition (1962). The use of the round logo and griffin trademark suggests the early part of this date range, but those marks are not definitive.
