You need bearing cups.

You are missing the headtube cups/races: (the two middle pieces, upper and lower headtube races)
They are probably the standard 1" size, and can be found on almost any older scrap bicycle.

What is the ID of the headtube? What is the OD of the cups, at insertion? There are at least 3 commonly available sizes of "one inch" headsets
Yeah, all that plus French and some more obscure sizes.
Even if/when you get the right headset, it's still going to be too wide to go into the headtube by hand. You'll need to use a press to get it in. It needs to be .1 or .2mm "too big" in order to press in securely. But, if it's too big, you could damage the headtube.
It appears that you have an older Schwinn reversed race being used as a lock nut, so that is probably the size of headset pieces that you need to use. They are indeed smaller I.D. than most common sets. As previously noted, there are more than one size of outer bearing race for 1". While they should not be loose, if major force is required it's probably not the right one, and could crack your head tube. Good luck.
