label: Description
content: 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).
