We can confirm from Company records and the style of writing in the form of the makers mark on the theodolite that this instrument is much earlier and As mentioned dates to the mid nineteenth century. This is fabulously engineered and is a lovely piece and it clearly sits on top of a tripod. This theodolite telescope was discovered with 2 other items, we have listed both of these, there is the tripod (as mentioned) this has extendable legs, and is a number 28, Mark 1, and secondly, a WW 2 Military Artillery Director.
They may have been used together. This comes in its original fitted wooden mahogany box. This has some wear but is still useable.
Again, this was a quality made piece. The shield shaped escutcheon around the keyhole is missing. The brass lock is present but there is no key.The lid closes with 2 brass rotating hooks. It can be secured but one of the hook tops is missing. This has 2 substantial working brass hinges. This is a fabulous and early Scientific Instrument and very collectable.
