My old man is getting rid of an old electric compressor, unkown cfm, it can't be more than 2 or 3, but you can adjust the release valve to get what ever head of pressure you want. Its a bit Dickie but works fine. Free if you come and get it from north-west Edinburgh.
EDIT:
Pics, it's an old old thing, needs a tug on the alloy wheel to run, but it works just fine. We'll be leaving the modern union we put on it.
