An Exceptionally Fine Presentation Rosenhain Metallurgical Microscope
English, dated 1914 from the beck records, engraved to the rear of the foot ‘ROSENHAIN METALLURGICAL MICROSCOPE PATENT R & J Beck London 30170’ and engraved along the front foot ‘TO MAWDSLEY BROOKE FROM H. HOLLINGSWORTH FEBUARY 10TH 1914’, the microscope is on a large and heavy foot with massive trunnions supporting the curved brass body, focusing is via 2 large wheels acting on a diagonal rack, fine focus is via a screw at the base of the stage, the stage has X-Y control via rackwork and can be fully rotated, an unusual and possibly unique addition of a reflected light stage is included with a mirror in a gimbal to one side with a 90deg prism, adjustable aperture and ABBE-type condenser, above this is a stage with clips. When not in use this unusual stage is removed and stored in the case, the body tube is fixed and has 3 apertures with covers to allow an early electric light and reflector to be used for transmitted light down through the objective, at the top is an unusual cam operated fine focus mechanism with pullys to be operated from behind a camera for photomicrography, the microscope comes with a large table condenser objectives and eyepieces all in the original French polished mahogany case with glazed door and large brass carry handle case height 41cm
Footnote: the microscope is unique as it is fitted for both transmitted and reflected light. The Rosenhain microscope was only for metallurgical opaque work so this addition of a stage for transmitted light must have been a one off special order. It was never advertised in any of the catalogues.
Mawdsley Brooke, was the son of JW Brooke, founder of The Brooke Motor Company in Lowestoft, he played a pivotal role in the company's history. Initially, the company focused on supplying ironworks to the fishing industry. However, it was Mawdsley's encounter with a Mr Estcourt on the Norfolk Broads in 1894 that sparked his fascination with the combustion engine.
Inspired by this encounter, Mawdsley took the lead in developing a combustion engine at their Lowestoft works. Incorporating several of Mr Estcourt's patented inventions, the company created Brooke-branded vehicles. Although the motor car business eventually phased out, Mawdsley's passion for marine launches persisted.
Under Mawdsley's guidance, the marine launch division of The Brooke Motor Company thrived, achieving both significant business success and personal racing triumphs. Mawdsley's dedication and innovation became synonymous with the enduring success of Mawdsley Brook's division within The Brooke Motor Company.
