Crewmen passing 40mm rounds on board US Navy ship in 1945

Robert Colla (a Ventura, California Adult Education instructor) came across what must have been a WWII-era 40mm Bofors Anti-Aircraft round “years ago” while hunting, brought it home as a souvenir, and proceeded to use it as a paperweight.

On Monday the Ventura County Star reports, Mr. Colla brought that paperweight down on an insect he found crawling across his desk with disastrous results.
