Hi!
You probably already noticed an interesting auction (quite related to this discussion)
http://cgi.ebay.com/US-MILITARY-M-9-...item588d15e7c8.
I think this one is really interesting: first style blade with fuller, black finish, Lan-Cay marking.
As a side note: about the 200 of the first style blades that in 1995 were "
placed aside in the factory as the blade tips were a fraction of an inch thinner then the specification called for" and ended with a first contract blade with black finish.
As far as I know these rare blades are all marked LanCay.
I have only seen pictures of these M9s without the blood groove.
Do examples with the fuller actually exist?
