Click the flag to start the clock! Click on that white rectangle to place a sheet of it into the clock, then click the lever sticking out of the base to punch the time on it. Click on the red cross to delete all the punched times. Click the button on bottom right corner if you want to turn on/off ticking.
Not too sure who made this clock. This clock has been refurbished again so you can always see the punched times. Punch/Bundy Clock (Button) available: https://scratch.mit.edu/projects/543804791/
