Vintage pair childrens hand knit sweater vests

Description

Sweetest beautifully fine hand knit sweater vests.  Best I can tell from the measurements they are about a size 5/6?
The yellow vest has some yarn that is slightly different in color, I don't think it makes a difference to the look and quality of the vest, I just wanted to point this detail out.  On the back of the yellow vest, it appears the knitter had some weave in of sorts.
Measurements are 10" across the shoulders. From back edge of neck to bottom edge 14" from front of v neck to bottom edge 8.5".  The armholes measure 6.5"   Across the bottom the width is 12" the ribbing measure 10" from edge to edge.
I put the content as wool as there are no tags, but if it is wools it's not scratchy.  But they are definitely a natural fiber.
Thank you for looking
