Troughton & Simms Theodolite
In original box
Beautiful original surveyor's level manufactured by Troughton & Simms in the 19th Century. The Theodolite itself is made of brass and is engraved 'Troughton & Simms, London'. It is a high quality instrument with its own circular compass below the telescope and two spirit levels. The barrel of the telescope extends out and is controlled by a knob further back on the instrument. The Theodolite screws into a mount that could then sit atop a tripod or similar.
It comes in its original fitted box which has a gorgeous aged patina and lots of signs of wear and use. Inside the box is also a spare lens. In the lid of the box is a paper label saying that the instrument was "Repaired and Adjusted by Cooke.Troughton & Simms". The label is dated May 1931 which shows its authenticity and use, however manufacture would have been earlier than this and is likely to pre-date 1900.
It truly is a stunning instrument and it is in excellent condition. The brass has been polished to a high standard and the parts cleaned and lubricated. The lenses are undamaged however they show the usual level of slight fogginess associated with an instrument of this age and there are some small specks on the lenses.
The theodolite measures 14" long, plus some further extension.
