Edit:-

I took the camshaft to a machine shop to see what they thought - they said I was better off getting a new one with new followers (I had made it clear previously that I wasn't going to buy it from them!)... so that's what I'm doing now. Thanks for your help everyone - seeing things in real life is always different from photographs...
