Usage/History: This is a student grade weight set,
used for routine mass determinations in conjunction with an analytical
balance. The quality of this set would indicate its intended
use in beginning chemistry or physics courses. Such sets might
also find use commercially for routine work.
An early description of Weights and their use is provided
below:
Weightsin Krayer, The Use and Care of a Balance
(1913)
Description: Gram weight set, 1-100g (1,1,?,2,5,10,10,20,50,100;

some of original finish missing on weights, fractional weights
and forceps are replacements. The weight set is held in a light
mahogany ? case (138 x 92 x 49mm) with a molded Bakelite compartment
for the fractional weights, the gram weights fitting into recesses
in a velvet covered and lined wood block. There is a small brass

through two encased hinges. The remains of a BKH decal are visible
on the top center of the lid, with Braun-Kneckt-Heiman-Co. /
Germany stamped in the case body on the left outside. There is
an oval brass tag, stamped HUMBOLDT S-T-C
/ 2085, attached with brass pins to the lower right of the right
side of the case.
Research: The catalog illustration is of a similar,
though not identical, weight set from the 1934 Braun catalog.
The Braun and B-K-H Corporations were apparerntly the Los Angeles
and San Francisco offices, respectively, of the same company.
