Knitting Needles - Lots (Ware SG12)

Retrieved from my mother’s house. I know nothing about knitting but these seem to be of two types - metric measured in mm and ‘imperial’ where a number denotes the size. An expert would no doubt know how the two systems equated but I’m not that person. Some are plastic, mostly the larger ones and some are metal. All are in matching pairs. There are also a few needles pointed at both ends.
