A few “thingies”
Left Hammer with Hammer Stirrup
Three parts here. The hammer and the stirrup are joined by the Mainspring Pin, which appears to be lightly staked. Discretion says not to disassemble, although the pin can be punched out if need be, for example to replace a cracked or broken hammer or stirrup. The last three digits of the serial number are stamped on the inside face. The outside face is smooth. The same applies to the Right Hammer, allowing one to correctly determine left or right hammer in the event of forgetting the correct orientation. The hammer rotates on the hammer screw to the cocked or fired position. There is a cut out on the hammer stirrup that fits approximately 1/4 of the circumference of the hammer screw, which allows for its required movement to stay in place in the mainspring plunger when the mainspring is compressed or extended.
