DESCRIPTION:Marked:Broad ArrowW. WATSON & SONSLONDON190027Arrow marks to Eye-piece
The engineering is of the highest quality as is demonstrated by the ease of operation of the tubes and the precision of the threads which facilitates disassembly for cleaning. The optics are stunning and adjustment is simple. Focusing is precise and the images sharp. This is an instrument usable over immensely long distances.* Removable sun-shield. The section of the barrel it is mounted on is also threaded and could be removed for maintenance purposes if required.* Two Draw brass tubular construction. Magnification 60x* Achromatic Objective or Field Lens 2.25 in diameter* Schryle-Huygens 4 lens configuration in two brass cartridges mounted in Draw 1* Weight and length require two men and preferably a tripod to operate it.* Sturdy leather carrying case.OPERATION:After fully extending the telescope, focusing is by adjustment of the First Draw. CONDITION: Outstandingly good for the period. The 2.25 Twin element separable lens is without scratches. All other lenses are easily removable for cleaning since they are individually threaded in to the brass cartridges which contain them in the First Draw. All leather sections are intact but the stitching has suffered some deterioration.The tube connecting threads are also easy to disassemble. Some flakes to edge of flint lens but this has no effect on vision since the area of the flakes are completely masked by the objective lens mount. They are only visible when the twin component lens is disassembled for cleaning.
FAULTS:There are none of any significance but the following points should be noted.* The tubes might well have been blackened originally but they now appear as clean brass.* Some scuffing and minor discolouration to the leather body and lens protection cap, consistent with age and use.CONSTRUCTION / ASSEMBLYAfter unthreading the eye-piece, the 1 & 11/16 ” cartridge can be unscrewed and removed from the first draw.
