1176. A quail hunter's bird call, to use: hold the leather part between your index and middle finger, and hit your index finger with the other hand, this makes a clean "cheep" sound.



In Catalonia it's known as a botet.



















1177. A spanner wrench, this particular one is for use on strainer lock nuts, text on it reads "Chicago Specialty Mfg. Co., No. 3003".


















1178. A multi-head hammer, not sure exactly who would have used it, possibly a tinsmith.



It was made by the M. & H. Tool Company, in Springfield, Ohio.
