WRAY LONDON Refracting Telescope Objective Achromat Antique Brass Lens RARE

Description: This sale is for a brass cased Achromat Doublet Objective lens engraved 'Wray London' Most likely originally intended for a Refracting Telescope of some kind. Maker: Wray London Hard to date precisely but I would estimate Circa 1880's.. Consists of two lens elements (not cemented) which appear to be flint + crown. There are two notches on edges of each lens element used to line up the elements & make sure they are in the correct orientation. I measured the focal length of the objective to be 1150mm approx. and with an aperture of 3"(76mm) the speed is approx. F15 Cosmetic condition: Really nice especially when considering age. Glass condition: Excellent. Clean/clear. Some small cleaning marks/ minor marks/light scratches and dust. Also comes with an additional brass optical part which is possibly an eyepiece for a telescope although unsure if it is related to this Wray objective. There is a small chip in the glass of the eyepiece. Measurements of the objective approx. Actual glass diameter when removed from mount: 3.1 inch (79mm) Visible diameter of glass when in mount (aperture) : 3 inch (76mm) Height of mount: 27mm Thread diameter: 84/85mm Widest diameter at front: 87mm Measurements of the eyepiece: height 7cm, 2.5cm barrel diameter , glass is 1.7cm diameter. Unpackaged weight: 373g A lovely looking item in its own right that could be used for display or parts for an existing telescope. Hopefully someone can use it to either complete an existing telescope that's missing its lens or perhaps use it as a base to build a new one from scratch. SOLD AS SEEN AND DESCRIBED!
