THIS IS A VINTAGE CORVETTE TRANSISTER DISTRIBUTOR FROM A CORVETTE SMALL BLOCK, I BELIEVE FROM THE 1960'S. I WAS TOLD THAT IT WORKED WHEN I BOUGHT. THE SELLER TOLD ME THAT HE USED IT IN A SMALL BLOCK CHEVY MOTOR. I AM ADVERTISING THIS AS FOR PARTS OR REPAIR BECAUSE I CANNOT GUARANTEE IT AS IN WORKING CONDITION AND SELLING AS IS.
