Does anyone know anything about the value of antique thermohydrometers. I have 2 in mint condition. My thermohydrometers are used for calculating the specific gravity of coal oil in order to figure out it's quality and molecular weight of hydrocarbons, i.e. what kind of petrolium products can be made from it. My guess is that they are over 100 years old. My guess is that they are very very rare as they're glass and easily broken. This is a little off topic for this forum but any help will be great.

One was made by C. J. Tagliabue Mfg. Co. in Brooklyn NY. It has hand written calibrations inside the glass. It has the precision grade # 199230L.

The other is Weston Elec. Inst. Corp. It's hand written too but has very little other identification info on it.

Dont know how old those are, but they are common in wine making as hydrometers to measure the sugar content.

Yeah! the guy that invented the alcohol hydrometer, C. J. Tagliabue Mfg. Co. in Brooklyn NY, made the nicer of my hydrometers.

Giuseppe Tagliabue

TAGLIABUE, Giuseppe, instrument-maker, born near Como, Italy, 10 August, 1812; died in Mount Vernon, New York, 7 May, 1878. He was educated at the village school, and was sent to Como to learn cabinet-making. In 1826 he went to London, where he was apprenticed to a firm of meteorological and philosophical instrument-makers. He settled in New York in 1833, and soon acquired the reputation of being one of the most competent instrument-makers in this country. His hydrometer for the proving of whiskey was adopted by the United States internal revenue department in preference to all others, and he made instruments for the United States coast survey. He made a great variety of hydrometers, including original forms and new adaptations to meet the requirements of the advancement of science and manufacture. Several of the self-recording instruments in use in the Central park meteorological observatory are of his construction.

Hydrometers were very popular between 1919 and 1933. I remember asking my father what that was in the kitchen drawer.

I have about 15 of them from the 30s, some have federal tax stamps on the boxes.

I posted the origional question.

Being new to antiqing, how in the world do people find values of stuff off the beaten path? On the show Pawnstars, they always seem to have one of the foremost experts on hand.

For the thermo-hydrometers, I guess I should just start hitting up musuem people. Please, if you're reading this and have an incredibly wonderful brain containing the perfect person for me to talk to, why not post it real quick.

The easiest way to determine a value of anything is to put it on Ebay for $9.99. The world will tell you what they are willing to pay for it.

Did I miss something here? You asked if anyone has any info. and you got some responses that I thought were very informative. Pawnstars is just a show with plenty of outside resources that are most likely compensated in some fashion. Patience, and consideration will take you a long way in learning. I'll put my less than wonderful brain to work finding some MUSUEM people. Probably a very, very rare breed.
