The 401 can use two spools on the top; it has two spool pins on top. On this thread we're talking about having a second spool where the bobbin is. My Eldredge Two Spool has that. There is a little can for the bobbin case and the spool that fits in there is a wooden one that holds 125 yards of thread. Most bobbins hold about 35 yards. You can't buy thread on such a spool anymore, but people have been nice and have saved some of those old spools. My machine will also wind thread on that spool from other larger spools.
