Yes I have there are actually two variations of this pouch a small one and a larger one, but both pouches hold 11 rounds instead of the customary 12 rounds also the USMC on the flap is also a different size but both pouches have the same markings on the inside of the flap and it is marked as follows
POUCH SHOTGUN SHELL
XM 7653
M67230-87-M-0222
LONDON BRIDGE TRADING CO.
VIRGINIA BEACH VA.USA.
