Apple M0130 400k external floppy disk drive. Cleaned inside and out, re-greased and work perfectly. While I can't promise you won't find something cosmetically wrong like a scuff or scratch (the one in the photo has one small pry mark on either side of the case on the left side towards the front), these look Nice!
Introduced in 1984 it was designed to work with the 128K and 512K. It will work with the 512Ke, Plus and SE (non FDHD). Apple advised not to use this drive on a system with a 1.4mb internal drive.
