Doom -
Storm did own it at one point, but I believe Phil C (900 Global) bought Dynothane from Storm and for a period of time, Storm produced Dynothane balls for Phil. Phil eventually took Dynothane production to Columbia 300 and Phil became a manager with Columbia Industries....then Columbia was purchased by Ebonite, and all brands under the Columbia umbrella went to Ebonite. For a period of time Ebonite continued to produce some Dynothane labeled balls for overseas bowlers......
Haven't heard much of Dyno in the past few years...
