J. C. Petmecky was an interesting fellow! A Hungarian immigrant, his work in Texas also included the making of spurs. He offered an alternative to the heavy Mexican spur and it was said his work was beloved by the Texas Rangers. He is largely credited with developing the OK style spur, which Buermann Manufactturing later sold by the ton. He may or may not have sold Buermann the rights.
