The hook like things are extractors but I can't say I've seen those washer thinkings on an Enfield, they seem to be shims based on the numbers on them.
They look sort of like No.4 extractors but they seem different( maybe 7.62 or .22) and seeing you got the numbered washers at the same time they MAY be gauges to check extractor fit. But really just guessing.
They are Cno7 extractors for the 22 rifles. I can't say that I recognise the washers. Can you show them again with something (ie a penny) to get a better idea of their size?
Extractors are 22LR used in the CNo7; the washers are stock bolt washers to ensure that the stock bolt does not project too far beyond the butt socket and put too much pressure on the forend thus cracking it. FYI, Ron
