Here are 3 of 5 currently listed colors for these CD 104 NET [075] Hemingray products:

L-R: Blue Aqua, Yellow Green, Blue

I'm still searching for ones in Aqua & Light Aqua, which you'd think would be the "easiest" to find (relatively speaking). Gene Hawkins and I chatted about these at the 2021 National and he estimates there are around 2 dozen known at this point. Keep your eyes peeled for these sleepers!

Shaun Kotlarsky has also written up an excellent article on how to identify the Hemingray-made ones: https://hemingray.net/articles/cd-104-net/
