Yep, that is similar to Junker & Ruh. Here is mine from the end when I got it cleaned up. It has a spring that you can see on the left side. It also has felt on the inside the part that flips down.

The Junker has felt on both sides of the disc (that looks like two discs) of the Tension Pulley per when I took it apart.

I didn't take the lower thread guide (the one that has check spring) so can't help with that.
I also sent you an email to address for Colorado get-together.
