Brass fraternity key for Pi Tau Sigma (ΠTΣ), the national mechanical engineering honor society. This is a substantial, ceremonial piece

8" in length and tipping the scales at a 1 pound 10 ounces of solid brass.

Dating to roughly the 1950s or early 1960s, it carries the kind of aged patina and character that only decades of time can produce. The weight alone speaks to the quality of the original casting, and at 60 to 75 years old this is a genuine vintage artifact of American academic and fraternal tradition.

A rare find for collectors of fraternal regalia, engineering history, or mid-century Americana, and a deeply meaningful piece for any Pi Tau Sigma alumnus who appreciates where the society has been. Pictures are of the actual item. Please feel free to ask for any additional information or questions you may have.
