United States Gypsum Company plant at Sperry, Iowa

Sperry, Iowa, appears in the sources as one of the United States Gypsum Company's plants for its fireproofing plaster: a 1990 EPA notice that published what USG reported said "Red Top Firecode Plaster (D)" was made "1959 to 1964 at 12 plants," and Sperry is among the plants it names.¹ That plaster is Firecode D; USG's sworn answers in a 1986 lawsuit give it the same years, "First Produced 1959" and "Last Produced 1964," and its asbestos as "Approximately 12% by volume," a figure for the product in general, not for Sperry's output in particular.²
