I noticed the photo gallery didn't have one, so I thought I'd add it.

One of two known. This one entered the main stream of the hobby in 1998.

CD 239.2 (F-Skirt) KIMBLE-850-1 (R-Skirt) MADE IN U.S.A./1-54 CB

This piece is fairly good sized, measuring about 7" in diameter and 5 1/4" tall.

Likely an experimental piece, perhaps found in the Hemingray dump decades ago, as it has a little etching.
