I have inherited a lot of vintage loading equipment. Pictures enclosed of some. These are a mixture of Ideal & Lyman. None of the dies are marked as to cal. , like 30-06, 257 Roberts, etc. Only numbers like 123, or 166, on the Ideal dies. . There are two or three that have a number stamp on the very top, like 257, or 308, 311.The older Ideal nutcracker handle is stamped with 30-06. Any help would be very much appreciated. Totally confused. I know the person who these came from did load for the 257 Roberts & 30-06, but other cals also. HELP!!Attachment 308022Attachment 308023
