Addiator Addfeet Junior
Stylus Addiator.
The 4 colmns on the left are for feet, then the column second from the right is for inches, and the column on the right is for 1/8ths inches.
The calculator pictured on the left and below shows 1,234 feet, 11 7/8 inches.
Designed principally for addition and subtraction.
42 x 160 x 5 mm (1.7" x 6.3" x 0.2").
Made in Germany.
With this calculator is the original sales invoice from when it was bought new. It is dated May 1982, from Midwest Surveyors Service, and it cost $19.95.
This is a very late date for purchasing a new mechanical calculator, but there were few electronic feet & inch calculators available at the time, such as the Addometer, and they were probably more expensive.
