Reproduction E. Howard No. 49 Astronomical Regulator. The original E. Howard astronomical regulators have soared to prices that are out of reach for most collectors. This fine quality reproduction is a compelling alternative at a tiny fraction of the price. The highly carved and beautifully finished mahogany case is 91" tall, 30" wide and 10" deep. The engraved and silvered brass dial is 16" in diameter and is 1/8" thick. The steel hands are blued. The E. Howard signed movement has jeweled pallets. The 4 jar mercury pendulum is in the style of the original Howard pendulum but is a reproduction. The glass jars of the pendulum have lead shot instead of mercury but mercury could be substituted to provide the temperature compensation of the original pendulums. The beat scale in thick brass, finely engraved and silvered. As expected the clock is a fine timekeeper.
