BROADHURST CLARKSON 60mm 4 DRAW SAFARI / STALKING / SPORTING / LONG DISTANCE TELESCOPE. DESCRIPTION:A well-engineered and very heavy instrument due to the grade of brass used in the construction. This precision instrument dates from the interwar period (c.1930s)This is an immensely powerful and versatile instrument which is simple both to deploy and focus and lends itself to a variety of stalking, sporting or other long distance applications. Because of its weight, it should ideally be supported by a tripod or rested on a firm surface.The lenses are very high quality as is normal with this manufacturer. All lenses are intact and in perfect condition and easily accessible for cleaning purposes. Threaded brass eye-piece. First Draw containing a 1.75″ / 4.5cm brass cartridge holding individually mounted Lenses 1 & 2 This cartridge canbe pulled out once the eye-piece is unscrewed.The Second Draw contains a second 2.5″ / 6.3cm cartridge containing Lenses 3 & 4, each individually mounted and easily removable for cleaning.Focusing is achieved as in any normal 4 Draw telescope – by extending the 4 draws fully and by then pushing in the First Draw until the object comes into focus.The 60mm Achromatic Objective lens has the usual two components of a Crown and Flint lens. Once the principal mount is unthreaded and removed from the barrel, it would possible to remove the secondary mount for the two lenses and separate them for cleaning if necessary. There is, however, no indicastion that this procedure has been necessary. Both sides of the Achromatic lens are in clean condition.The 90mm / 3.5 ” sun-shield moves positively and without any play. The section of the brass barrel on which it is mounted can be completely unthreaded and removed from the main barrel / The sun-shade can then be slid back to provide access to the mount for the Objectve, Achromatic Lens.This is a precision instrument which has been finely engineered. All threads and connectors work perfectly. The leather cladding to the barrels, the lens caps and the carrying strap are all in good, well-polished condition. The lens caps each have their original red velvet discs and very smooth interiors which are in excellent condition. The strap is in good condition, bu, that said, because of the age of the strap and the weight of the instrument, it would be prudent to inspect the strap regularly and replace it when deemed necessary. Leather straps do not last for ever and sudden stresses can cause old straps to snap.The anodised draw tubes have not been cleaned. The darkened surfaces were intended to avoid reflections when the instrument was in use. The original coatings are still in excellent condition.Makers marks engraved to the First Draw:BROADHURST CLARKSON & CO.LTD / 63 FARRINGDON ROAD / LONDON. E.C.(Although the address postcode was changed in 1918, the makers appear to have continued using it for decades.)SPECIFICATIONSLENGTH: Closed : 29.4cm / 11.5″ With 4 Draws fully extended: 97.7CM / With the 9cm / 3.5″ sunshield delpoyed fully: 102.4cm / / 40.25″WEIGHT: 1.850kg inclusive of lens caps and carrying strap FAULTS: None apparent to the telescope. There are some slight surface scratches and a very minor indentation to the leather clad barrel. This minor indentation has absolutely no effect on the smooth operation of the Fourth Draw so it is clearly only in the leather itself. There does appear to be an area of slight weakness in the carrying strap, close to the buckle.SUMMARY:An excellent and versatile, well-engineered instrument for the serious user or collector. This is a very good example of one of the leading branded instruments during the inter-war years for explorers on excursions, game hunters and stalkers. The two main manufacturers were Dollond and Broadhurst Clarkson . Neither manufacturer assigned serial numbers to them so their precise year of manufacture is always an estimate based on general condition. The excellent leatherwork suggests that this is a late 1920s or early 1930s model. It will be carefully packed and insulated to our usual high standards for fully insured shipping worldwide.
