Chrysler Corporation, Detroit MI
Chrysler built 9002 steel pontoons for the Navy at its Jefferson Avenue plant at the foot of Conner Street, in Detroit, (still active today), where it also made its marine engines. They then combined the two product lines, building 8,229 "Sea Mules", which were powered and steerable pontoons. See an ad for Sea Mules here. See the plant from the air on Google here.
