LET-R-WAY
letter scale

This handheld letter scale is from the U.S.A. and weighs up to 4 ounces.
The scale has stripes of measure at 0, ½, 1, 1½, 2, 3 and 4 ounces. The instructions are printed on the envelope in which the letter scale was delivered. The specified letter rate of 3 dollar cents per ounce was valid in the period 1932-1958. The airmail rate of 8 dollar cents per ounce was valid in de period 1944-1946. Therefore this letter scale is from the relatively short period 1944-1946.
