The Handy postal scales is an unequal-armed scale of the type bismar. The counterweight and the load both have fixed positions,
an equilibrium is found by moving the suspension point. The Handy has on one side a scale in ounces with N (0), ½, 1, 2, 3, 4, 5, 6, 7, 8 ounces
and then 1 Lbs (16 ounces). On the other side is the name of the letter scale, the maker, a patent number and a short list of postal rates.
The maker of the Handy postal scales is Maasstrone Mfg. Co, Battle Creek, Michigan. The patent number 373269 does not appear to be the real patent number,
but it is the serial number of the patent application of 24 June 1929. The right patent is US1,872,646 of August 23, 1932 and is in the name of Henry J. Behrens
from Lowville, New York. There are Handy postal scales with the name Behrens & Co. See the article about the Handy Postal Scales
by Utz Schmidt in Equilibrium 2007, issue No. 2, pp.3242-3243. The postal rate of 2 cents per ounce was valid in the period 1919 to 6 July 1932.

MN, stamped pat, no. 373269, on the beam, but that patent is completely irrelevant, being issued in 1888. for a music turner. Mistake? Fraud?
