D C Flexstone (Johns-Manville)

D C Flexstone was a Johns-Manville weatherproof jacket; J-M's own lists spell the name out as "Double-Coated Flexstone."1,2 In sworn answers in two lawsuits, given in 1969 and 1970, J-M described it as "An asphalt-saturated asbestos felt coated with a mineral-filled asphalt."1,2

An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, files it among papers, felts and blankets, and gives it as made from 1929 to 1981; 1981 is the list's own year, so it may still have been made then.3
