Vintage ALTENEDER Drafting / Engineering Tool. “Spacing Dividers” or “Equal Space Divider” Model 1720.  Used to divide lines or spaces into equal parts, this is one of their earliest versions as denoted by the arching shape of the name engraved on the tool. Made in the USA (Philadelphia) by America’s premier drafting tool maker, it is also called an “Eleven (or Ten??) Point Divider”.   Measuring nearly 12 ½ ” top to bottom when closed, it opens to maximum width of over 19”.  In excellent, very lightly used, condition it very cleanly shows that arched ALTENEDER name engraved on one side and numbers on the points.  Coming to you in its original box with the original (and still nice) ALTENEDER seal on the inside bottom. The points (very sharp!) and the entire mechanism is stainless steel.   Very useful in certain drafting or shop applications. Not a common version (or size) and it will make a great addition to your collection or workroom.
