Does anyone if these still exist?

They have got to be at least 40 years old

Have a plastic threaded dowel to assemble pieces together end to end
to get whatever length you need.

My mother still had some when I closed up her place in 2007.

She was in Apple Creek area (30 miles west of Canton)

I'd start with Lehman hd'we in Kidron or maybe a Farm & Fleet type
store.

Check the hd'we stores that serve the Amish like Lehman above.

Have fun.
