Sediver 10 inch clear glass suspension, normal profile with clevis. VFO 92

VFO stands for "Vidreria Industria Figuerras Oliveiras S.A." and are made in Brazil. At some point Sediver had a factory in Brazil that produced insulators. Perhaps Sediver bought the plant that made VFO glass and had their caps installed. If anyone cares to share some info on the subject, I'd be pleased to include it here, with credit of course.
