    Hi , We recently purchased a G.H.Zeal London England Hydrometer at a Auction & would like to know more about this unusual Item. The Hydrometer with no temp markings is mounted on a black steel plate with markings of from 90 to 110 on the top & Low 103 High on the bottom either side of the Hydrometer & a long wire clip at the back ,we think to hook onto a wing maybe. It is about 122mm Long x 47mm tapering down to 35mm. It has a brown leather case similar to a Spectacle case Please let us know what is the instruments purpose & approx Value . Regards Alex & Susan
