I am looking for information on if or what parts the Auto Ordnance Corp/Maguire Industries might have made for the water cooled Browning Guns during WWII. I know that they made barrels and other small parts for the BAR as well as parts for IBM during the M1 carbine contact. I ask as there is a picture of a float AOC made after the war to display all the items they were involved in....and in this picture they show a water cooled browning. Any help??
