Zannoni and his business partner R. C. Flemming re-established another company called Rubber Crafters, which operated for several years.

Businessman Zannoni has continued to operate a local company in Grantsville, Sav-a-Tool, which has provided several jobs to the community.

Funeral arrangements will be completed at the Stump Funeral Home in Grantsville.
