Surveyor's level made by Joseph Jackson, Strand, London, 1735-60. Signed 'Jos: Jackson LONDON'.
Brass surveyor's level with spirit level and telescope. There is no compass and the tripod and objective lens for the telescope are not present. This instrument is similar to the standard type of Sisson level in common use during the period, but the bar carrying the telescope and level is not adjustable.
