Rather than start from old design, you might just want to look at the
online design tools and matching core selections for "simple switcher"
boost and buck datasheets/app notes, or SG3524 type transformer converters.

The major distributors carry inductors in their catalogs that are just to
match the simple switcher series.

PC-clone power supply transformers - can be unwound and then rewound with
new windings - are often used with SG3524 type designs.
