Hi there, currently on the lookout for a good unpolished Carrera 3647n, and at least 50% I'm seeing for sale have the longer tail chrono hands seen on later models like the Camaro. As far as I know the 1dt execution Carreras all had the short-tail hands (designed probably to not overlap the hour subdial on the 2447) If they are there, I'm pretty sure these would be replacement service hands. Does anyone know for sure? Just looking to make sure what ever I get is correct. Thanks! David
