Place Made: London, England. Materials: Leatherette outside, lining black inside, Bakelite instrument itself. 17 cm x W. 9 cm x D. Outside of case was originally stamped on the top in gold lettering Hawksley CRISTA London (now very worn but still legible). Blood measuring device in black has stamped on it in gold writing Hawksley Crista London. SAHLI 100%=14GRAMS Hb PER 100 C. Original glass tube that sits in this device with graduations on it and the Hawksley Sahli name engraved on it. Black round container with a screw off top and a glass tube inside. Small glass tube with a cork in it. One round glass stick that looks like a mixing, or stirring device. Glass and opaque glass tube connected with a rubber tube (good condition) to a smaller glass tube at the other end of it. Written on the tube is Hawksley London 20CMM. Glass tube with a rubber squeezy bulb on the end. The rubber bulb is hard (complete) but it has not perished. This would explain it being Bakelite which was in any event phased out during World War 2. See all 3 photos.
