Straight 1" OD quill stem for Townie
Sounds like you have a ~60mm stem   Quill stems are available in lengths from 20mm up to over a hundred mm.

Your other option is to rotate the handlebars so they get a bit closer, or possibly pull your saddle further forward on its rails.  These might be worth trying anyway - they're free fixes and you can always revert.

If you want, you could replace your quill stem with a quill/threadless adapter and then fit a modern stem.  There are many more threadless stems available nowdays, including adjustable ones which might suit you.
