Tycos "Stormograph" Barographstar rating 5ArnoldOctober 5, 2010I am 73 years of age and obtained one of these from a "weatherman" in 1964.The words: "patent 1907 are enscribed in the Brass Plate under the drum. Exact item in "I think Walnut Wood" except my case has a drawer. Performs precisely and never misses a beat. Use it only when storms are around here on East Coast of Australia.Looks just like the you have pictured but wit the drawer. Would NOT sell mine even if offered $2,000.00 I also have a few discarded terrific PLUVIOGRAPHS extremely accurate.
