Lot of 4 AS IS IBM PC Convertible Floppy 3.5 Disk Drives, Two known not to work

Description

Up for buy it now are the 4x IBM PC Convertible 5140 floppy disk drives shown sold in AS IS / PARTS ONLY condition. The two black cased ones are made by Toshiba and in my experience typically read better from a variety of floppy disks, however the two included in this listing I was not able to get to work with limited testing and those should be assumed bad.  The two silver cased drives are made by ALPS and have not been tested, primarily because the ALPS drives are a bit picky with the floppies that they will read even if they are working, so I don't want to say that they won't give you issues with reading some disks, but there is a fair chance they will work if you are using older floppies. One drive also has a part of the lower plastic chipped off of the face plate as can be seen in the photos, but faceplates are interchangeable between both types of drives if you end up swapping them.
This is one single lot for the 4 drives shown and they will ship in a medium flat rate box anywhere in the USA as they are fairly heavy. The idea is that these may be usable for parts to make other drives work, and buying these 4 together will likely cost less than the shipping you'll pay elsewhere for 4 separate drives as they are pretty heavy. I'd rather not see them be put to use by someone who knows what
they
are doing than be recycled.
USA shipping will be free.
