1923-ish I think, and maybe a 350, but Raleigh numbers are a bit scrambled so you'd have to call in the VMCC Raleigh marque expert if you wanted the definitive ID and date.
It would be a nice little bike, but also a significant restoration project. It could be restored if you want to do it, as parts are probably not to difficult to find.
You might want to find out exactly what you've got before you decide.
