Item History & Price
Reference Number: Avaluer:14251840 | Country/Region of Manufacture: United States |
1938
Estate find. This Dietzgen slide rule is in nice vintage condition. The leather case show wear, including separation on the seams on the top (photo 9). "4 6th C.B." is lightly scratched into the leather (photo 10).
This is marked as the 1750 model. The 1750P model has been dated as 1938, so I guess this is 1938 or earlier.
