PROTOTYPE SCABBARD : PHROBIS / BUCK

About the XM9 green scabbard : POUCH : 15 made to go with the first design web gear/back.

The ultra rare M9 BAYONET XM9 by PHROBIS made for the ARMY BAYONET TRIALS XM9 PROGRAM ( 1986 )

With the SEAL PROTOTYPE BUCK 184 SHEATHS
camo green & desert tan, an PROTOTYPE LARGE POUCH with two Velcro attachments.
These 2 PROTOTYPE BUCK 184 SHEATHS / SCABBARDS
were made when the U.S. NAVY SEALs and PHROBIS were working together, in 1986.
Maybe 10 or 20 pieces according Rick MacDonald. They were produced only one time, in 1985.
Infos from the BUCKMASTER BOOK page 174 & 181, from Richard Neyman.

BUCK 184 with rare "CAMO POUCH"

Regarding two M9 suspensions, the one with LC-1 clip-plate is odd.
Web stone flap too short to snap on bottom of M9 scabbard, if mounted to standard location.
I think maybe brass ferrules to attach webbing maybe moved lower down on scabbard for this suspension.
May also be webbing strap was for something else or faulty, and was attached to upper clip only for demonstration purpose.
