Vintage(?) Laboratory Retort Stands - $20 (DeKalb)

Vintage Wooden Laboratory stands, out of a university laboratory built in the 1970s (Note: Not NIU).
I say "Vintage(?)" because I do not actually know the age of this equipment, and do not want to risk misrepresenting it.
The loose 4-funnel rack and test tube holder is meant for a metal retort stand.
I have one I can use for demonstration, but that is not for sale.
Wooden stands: $20, or $35 for both test tube racks: $2 apiece 4-funnel rack: $5 test tube holder: $5.
ceramic triangles: 50 cents apiece, or heck, free if you buy other stuff.
Will take offers for multiple items, just let me know.
