I have a Lee die that I do not know exactly which die I have. It is a crimp die marked Lee -45acp-F1. It has the new Lee gear type ring on it. Looks almost new. It has a internal sliding sleeve. I went to the Lee site and tried to find it on their listings and finally tried to send them a message to ask them to identify it, no joy. I will try to put up a couple of pictures. I need help. Thanks, james .
