Description
Condition: clean and running. Dana had done a lot of research on invar, and had added invar rods to many of his pendulums. This is an example of that change. See this clock pictured in Dana's book titled Vienna Regulators , page 114; you will see the invar pendulum in the foto. This model is nearly identical to the Lorenz Bob No. 28, and also was the most common model imported and resold by Kroeber (this one is not marked Kroeber) Height 45 inches
