1961 ZIPPO LIGHTER ADVERTISING GENERAL PRECISION

Slightly used Zippo from 1961 advertising a company named General Precision Librascope Division. I believe Zippo came out with this lighter advertising this company in 1961 as they were in active research involving silicone wafers. This lighter is in excellent plus condition. Shipping to anywhere in the U.S.A. by Priority Mail is $6.00 plus insurance if requested.
