Yankee Braces - A Type Study of Sorts
by George Langford
February 17, 2007

Group J - Two Occupied Japan copies of North Bros. 2101A-10 IN braces
made after all the patents had expired.

These two braces, nearly carbon copies of North Bros.' 2101-10 inch "YANKEE" braces, were made in occupied Japan.  The Second World War was over by the summer of 1945, and the last North Bros. patent had expired on August 1 of that year.  The upper brace is labelled, "CHROMEALLOY" over "Patt. NO 210" as well as "WITH" over "PROFESSIONALS" over "I.X.L." and "MADE IN OCCUPIED JAPAN."  The lower brace is labelled, "STEMOR" and "Occupied Japan."

Virtually all the chromium plating remains on each brace, and the only damage to either are the chips off the polymeric pad of the STEMOR brace, which has otherwise seen nearly no use.  The CHROMEALLOY brace actually got used, as its many small dings & scratches will attest.  The STEMOR brace's chuck is considerably larger in diameter than those of the standard North Bros. brace and the CHROMEALLOY brace.  The  handles of the CHROMEALLOY brace are both black-painted wood, but the STEMOR's wrist handle seems to have been molded much like the North Bros. braces, except that the material is a theromoplastic rather than a thermosetting composition like the "real" YANKEE braces.  Note that both braces have the complete complement of 3 oil holes.  They are also a little longer than standard YANKEE braces.

Both braces are fully and smoothly functional. 

The CHROMEALLOY brace, designated B&D-J1, is in the best condition and is priced at $75.00.

The STEMOR brace, designated B&D-J2,  has some chips out of its pad, so it is priced at $65.00.
