Those scoops probably came from Fiero Warehouse (now "Sage Glass Works").
There were 2-3 different styles. I have the IMSA (concave) style.
Sage (aka Tedd Wilson) still probably makes them, but he does it on a "per order" basis. He doesn't stock them like Fiero Warehouse used to. (He has always made them, even in the Fiero Wareouse days, however.)
You can reach him at sgwfiberglass@gmail.com One of my favorite vendors, and one of my favorite people, really.
