It sort of looks like a hydrometer but much (shorter). The numbers at the base start at 10, 15, 20 up to 40. (the reverse of how the numbers are on a hydrometer). I was cleaning out a box of my parents belongings, they used to make scratch wine, I am assuming they used this. Would like to put it to use, however not sure how. If this is not used for wine making any idea what it is used for?
