I just wanted to post about some of these cool locks that showed up to our meeting this week. A newbie showed up with a box full of fun things. Pictured below are an Egyptian lock that he says is some 300-400 years old, and the top-inside of a cash box. The Egyptian lock has pins in the top of the large piece that drop into the bar that slides back and forth. The wooden toothbrush-looking key is used to push up on those pins and pull the bar back.
Not pictured are a couple of Bramah locks that he brought in. You may have read about these locks.
