Sock heel

My elderly mum is looking for a sock pattern with a traditional heel like she used to knit. I’ve searched and searched but don’t know what it’s called. It just looks like a regular shop bought sock made by decreasing.
It’s not short rows or flap heel or any other of the other millions of patterns I’ve found. Does anyone know what it’s called?

Do you know if she was knitting the socks cuff down or toe up? Maybe more likely cuff down?
This is one compilation of sock heels with videos which may help narrow the type of heel down.

Here’s another with some links to patterns. (The videos seem to take time to appear.)

This is a single video that compares some sock heels.

Thank you so much!
