Chain saw (Penrith CA11)

This has been in the shed a couple of years...the chain had come off, and my son, in his wisdom took it all apart 😂, then can't remember how to put it back again 🤣🤣🤣 if you have a larl bit of knowledge, and the patience to go with it, it may still have a life. As far as I know all parts are there that should be, and possibly a couple that are unrelated, we can just look on that as an added bonus!
