This turnbuckle will fit the carburetor priming linkage of a 1912 Cadillac touring car.  It was patterned off of one found on a 1912 Cadillac touring car, but may work with other models of the 1912 Cadillac.    Comes as shown in the pictures.  Some finishing work may be required to complete.  One end of the turnbuckle is threaded #10-24 right hand and the other end is threaded #10-24 left hand.  The following list of parts included in this sale is from a 1912 Cadillac parts book.  This part will work with my listing for the complete primer linkage, unfortunately I only have one of the turnbuckles.  See my ebay listing 115601976015 for the compatible primer linkage.
