This product is a reproduction Commodore 128D Floppy Drive Lever for the european PAL (plastic) 128D with the built in handle.
This is a direct replacements for a broken lever on your 128D. Simply press them onto the shaft and you're off the the races. In my experience, the originals typically fail by splitting as over the years the strain (and age) takes it's toll. Because the shaft is recessed into the front of the case, without a replacement, it pretty much renders the drive un-usable.
Bring those old drives back into service with these super strong PLA, 3D printed door levers.
