Yes, John the 1720 pattern is the new number for the Imperial 1433 (I have this in many Imperial, Wiemar Eickhorn catalogs and even a printing block in wood with the number 1433.) Same item just updated the number in the 30s Yes the cross-guard is different on the one you have..but than I would say you have a 1720 (Imperial number 1433) with different cross-guard.. I hope everyone can follow this.... I was just looking in a much older Eickhorn catalog..
