I was going to send these pics to Ralf, but in my frustration at not being able to send a pic in my PM (I know there is a way, but this is faster) - I just decided to post/share this pic (s) this way.
In my last score of a huge lot of mixed MIJ & American goodies, I found this interesting key. My research indicated that it is a STAR key.
Thought I would share, as I have never seen a key like this before.
Ralf - feel free to use these pics and indeed let me know if you need any more pics.
