Chicago Roller Skate Company Early 1960's Betty Lytle Styled by Hyde

This is a vintage pair of Betty Lytle, styled by Hyde, women's roller skates.  The boot is a size 6. The plates are marked Chicago Roller Skate Co. Ware Bros. size 4.  They have Cottrell SilentRed wheels that are in decent shape.  They were purchased in the early 1960s, I did a little research on the owner who graduated high school in 1967. Please message me if I can provide additional information for sizing. The boots are in good condition with light scuff marks.  The wheels are lightly worn and still usable.  Also included is, what looks to be the original red case, marked with the original owners info. The case is also in pretty decent shape, fully functional. I am asking a fair price for these fully functioning roller skates, as they are a pretty rare find and in great shape.
