They are bent brass or steel. You could make your own from those,aluminum, or plastic. Or 3d-print them, for that matter. Or carve them out of wood, even. ;)
Thingiverse.com has them for the South bend 9" lathes, for example. I'd be willing to make photos of mine for you from my Atlas TH42, if that will help.
There are a lot of things that can be made, or 3d-printed, for your lathe. Some of it, other folks have already done the hard work, some you may have to do for yourself, but you'll have some fun and learn some neat stuff, too.
HTH!
