This folding cardboard case is covered with black leather and lined with blue leather. The inside of the lid flap is marked in silver: Made in Germany. It is also marked: Technical Supply Company (/) Scranton and New York. The firm's logo (intertwined letters T, S, and Co., in between two torches) is to the left of the first mark. The set includes:

2) 6" German silver and steel fixed-point dividers. On one side, the joint is marked: D.R.P. On the other side, the joint has the Schoenner logo: an S, G, and two intersecting arrows with two heads superimposed on each other. The inside of one leg has a drawing of a gear. Inside the other leg is marked: SCHOENNER, GERMANY ||.
3) 1" yellow metal cylindrical case with two pencil leads. The lid is marked: PNK TINGE. The bottom is marked: AVON PRODUCTS INC. (/) DSTR (/) N.Y.

The drawing pen and case for leads do not appear to be part of the original set. The case may have been manufactured for cosmetics instead of as a scientific instrument. Another instrument, probably a small pair of dividers, is missing.
Georg Schoenner (1821–1899) established an instrument workshop in Nuremberg, Germany in 1851. His son, Georg Schoenner Jr. (1851–1921), joined the firm in 1877, and his grandson, Georg Paul Schoenner, reorganized the business as a limited liability company in 1921. Schoenner exhibited at the 1876 Centennial Exposition in Philadelphia and the 1893 Columbian Exposition in Chicago. The firm targeted the U.S. in its sales, and was the largest producer of mathematical instruments in Germany before World War I. The company's interest in the American market is illustrated by the fact that Georg Schoenner Jr. received five U.S. patents in 1904 and another five in 1908. Similarly, the firm held the rights for the patent mentioned on the compass, for the design of the pivot joint.
Theodore Alteneder & Sons held the rights to the patents marked on the drawing pen. These covered the set-screw and latch on the pen point. For other drawing and calculating instruments manufactured by Alteneder, see 1991.0793.01, 1991.0793.05, and 2008.3041.01.
This set is not exactly like any of the sets of drawing instruments advertised in the Technical Supply Company's 1912 catalog.

I have a very similar set to this, however mine is labeled "U.S. BLUE COMPANY GERMANY" and the number 723. It's signed by an owner in 1920 but that's the only info I can find. Anyone have any insight?
Thank you so much for putting this on the internet! I have the very same drafting kit from my Grandfather who past away in 1973. He was born in 1894 and used it in his work. I was not sure if it belong to my Great-Grandfather as well. Now I know all the information on it and the date of Mfg. I believe now that it belonged to both. Thank you so much!!
