Rare Antique Griffin's Developing Tank Amazing piece of historical photographic equipment produced by John J. Griffin & Sons, a British manufacturer of scientific and photographic apparatus active in the late 19th and early 20th centuries. Designed to develop six glass plates and complete with the plate holder. I believe this was made around 1910 I have left it in uncleaned condition and the overall condition is very good for its age. It is missing the fastening to clasp down the lid on one side (see photo) The tank measures 12cm by 10cm. The overall length with the spout is 16.5cm
