Lot 133Price Realized: $688
|Lot 133: CD 186.2 HEMINGRAY Color: Clear Description: These are prone to some fracturing around the "nut" but this one is just about perfect! The whole CD 186.n series was formed by using the skirt of a single mold with various unique dome combinations. For over forty years, collectors wondered exactly what these might be used for and if the design was patented. It wasn't until several years ago that Bob Stahr found patent number 2,392,342 (January 8, 1946) which described this series as spark gap arrestors. Sometimes you feel like a "nut"! (#6894)|
Estimate: $500 - $600 Open: $10
