Ok all you rocket experts this is some off the wall motors I have ended up with.

1/2 A6-2 18mm?? about 20 years old that a buddy bought in a box at a garage sale.
What are the good for and are they worth making again?

Also have, but cannot find, some ?Black Diamond? maybe B16-4 18mm in a black and blue colored two pack of motors. What about these?
