Mt. Washington Ramshorn - 1870's

Mt. Washington Ramshorn


This ramshorn style is referred to as the Mt. Washington (New Hampshire) type as it is from the weather observatory at that location that they were used in the 1870's. This style is characterized by a metal hook encased in glass which, in turn, is encased in iron.

The glass comes in a range of colors including clear, straw, green, cobalt blue, and amber. Some colors are much scarcer than others. The wood blocks are found with only a fraction of the insulators. The weather conditions were so severe at this location that it is amazing that any wood survived at all.
