By 1944, Westinghouse was working on three derivatives of its first axial engine, the 19A. The largest of this family, the 24C (24 inch diameter), became the J34. The earliest flight I can find for the J34 is in 1947 powering the XF2D-1 Banshee.
The J34 had a long career with a few surviving into the 1980s.
