What have you done today with your Austin Seven
This sort of failure with that style of piston was not uncommon on other makes but the area of metal to finally fail was usually very small. Did a bearing run or cap loosen and allow the top ring to catch? Can also follow a cracked crown but evidence of blow by through the crack then usually evident.
