RECENT BARN FIND IN NORTH TEXAS. I BELIEVE THIS IS AN UPPER COOLANT OUTLET FOR AN AMERICAN AUSTIN FLATHEAD 750cc ENGINE FROM THE 1930s THROUGH 1940s. THIS MAY FIT MANY OTHER YEARS AND ENGINES. I FOUND THREE OF THESE, SALE IS FOR ONE. ALL HAVE TYPICAL SIGNS OF AGE AND USE; WEAR, CORROSION, ETC. I PICTURED THE NECK OF THE WORST ONE SO YOU CAN EXPECT THAT CONDITION OR BETTER. AS PICTURED, AS IS, USABLE, NO CRACKS.
