"...test-tube storage racks..."
Wish I still had mine! I liked to use them as a centerpiece with a single flower stem in each test tube. Country Cute!
Bought them for a song at that UW overstock store between Verona and Oregon - can't remember the name, but we'd go there on Fridays and find all sorts of TREASURES!
I know that place! UW SWAP. It’s where I got a freeze-dryer for less than $200. Along with some really awesome labratory glassware. They have a mass spectrometer up for sale right now!
They switched everything to online-only due to covid, but they’re still going.
