Description

#465       785       Unmarked.       Dark bubbly olive with amber.      

The cross-top threadless has been found in both the San Francisco and Sacramento, California areas.  To do date, we have confirmed only six to exist within the insulator collecting community  Of that small group, this one ranks as the second best condition, as near we can determine.  Some of the other examples have serious damage.

Telegraph line construction was limited in the state of California during the 1850's and even into the early 1860's; the time period these early hat style threadless were produced.  Although a manufacturer has not been confirmed, there is a possibility this type insulator was produced in the San Francisco area. One glasshouse was formed in San Francisco during the late 1850's and another in the early 1860's, suggesting a possible source of the cross-top threadless.

The cross-top design is highly unusual for an early pilgrim hat style insulator.  That factor, plus the western historical significance, rarity and super bubbly glass make this an exceptionally desirable insulator.

The attractive olive colored glass has amber impurities swirled within, plus is loaded with thousands of small, fizzy bubbles.  The glass is dark in density, yet still allows light to pass through some of the pinhole and skirt with window lighting or in a backlighted cabinet.  When viewed through one thickness of glass, plenty of light traverses throughout.

An amazing rarity with just one flat base chip.  Entire outer surface, including the damage prone cross-top, remain in exceptional condition!
