Name that Ware June 2021

The Ware for June 2021 is shown below.

This is, I think, the last from the Don Straney collection (thank you so much for helping to bridge me through the pandemic!). Maybe I’m showing a bit too much here to make it hard to guess, but, honestly, I had never seen the inside of one of these types of things before, and I probably never will in person; so I wanted to share more than less of its construction details. It’s kind of crazy what a rat’s nest it is on the inside; I particularly love the tiny loops of wire which I’m pretty sure are meant to serve as inductive elements, and not just jumpers.
