The back has scales for 3/8" to the foot, divided to 1/50" and numbered by twos from 0 to 30, and for 5/16" to the foot, divided to 1/30" and numbered by twos from 0 to 18.

- Keuffel & Esser began offering model 1419 in plastic in 1949. At $1.80, the instrument represented a significant savings over the $4.20 price for the boxwood version of model 1419. The trade-off was that the marks were not engine-divided. The firm changed its model numbers in 1962. According to the donor, the instrument was used by her husband, the electrical engineer Robert H. Wieler (1923–1993).
