Rare vintage zippo that was not included in the anniversary set. I cannot find this particular zippo referenced online or sold looking through the archives.

I found one similar zippo sold on a japanese auction site, but that was a polished variety with regular date under whereas this one is brushed steel with the 1932-1992 dating under.

I can also find a more common version with the "solid brass" stamped top lid, but no logo on the bottom part.
