Here's a test jig that our "lollipop" guy is selling minus tube.

Another case of greed, When he should just leave it complete. I am sure he is thinking he will get a bundle for that "test" tube and the test jig separately.
But you never know, He just might!

I had a chance to buy the exact same item from a guy that had it advertised on ARC in 1997, It was supposedly nos and he wanted 100.00 for it. Hmmm...

Probably, It is sandblasted on using a stencil from what I remember.
