Hello,
there is an M9 bayonet to commemorate the Panama 1989 "Operation Just Cause".
A picture of this commemorative can be found in the H. Brett book.
Unfortunately I don't have the book ready accessible, and I can't even remember if it was a Phrobis (most probably) or a LanCay.
I don't have any idea, also, about the production numbers of this bayonet.
Thank you for your question, by the way, as I suddenly realized I need one more commemorative for my collection
