A collection of four antique late 19th century surgical amputation saws including a large Charrière saw by H. Windler, a skull saw and two  metacarple saws, one marked Allen & Hanburys.
 
The  Charrière amputation saw is marked 'H. Windler', it is in good solid condition with small losses to the chrome plating in places, mainly the inside top of the handle. The saw measures 38cm (15"). H. Windler was a German surgical instrument maker active between 1851-1900, based in Berlin. 
 
The skull saw, with the two curved blades, measures 18.3cm (7.25") in length, the Science Museum in London has some in their collection, here is a link to a very similar example in their collection:

The two metacarple saws measure 20.5cm (8") in length, one is marked Allen and Hanburys Ltd London.
 
Medical items such as these were made to the highest quality standards as cost was not the main factor and they were necessarily made in small numbers and so are becoming increasingly rare. This is a substantial and important collection.
