Adams Universal Microscope
Adam's Universal Microscope - made by George Adams Snr. about 1755 for King George III, while he was still Prince of Wales. Probably the first microscope to be mounted on trunnions, an important improvement which was not persisted in. About a century later the method was revived and nowadays most microscopes are supported in this way. On display at The Science Museum in London. Date: circa 1910s
