About tngurl
I search high and low for all types of collectibles throughout the Midsouth. This includes auctions in big cities, auctions in small towns, estate sales and yard and garage sales.  I try to find extra good deals so I can share them with you.  I also make every effort to be as accurate as possible in describing each item.  And in the rare case of an overlooked flaw or in the case of my lack of understanding of the nuances of an item with which I have little familiarity, you can rest assured I will make it right.  Check my feedback and buy with confidence.
The Saybolt Standard Universal Viscosimeter Antique .
Information is limited unfortunately...Used to test the viscosity of oil in the early 20th century.. The only other example of one I came across was at the Smithsonian Museum Of American History which was dated to around 1915...Fantastic condition for being how old it is. Just a little bit of a unnoticeable depression around the rim which adds to the charm . If you have any other info feel free to email with knowledge...Thank You good luck
