Well, you are a new registsred user, 2 only posts, both on this topic, both today.Serious,
Could you photographed the markings on the run-out on your Meat Is Murder 12"? It would put everyone's mind at rest as to the authenticity of it.
I have a genuine copy and can confirm exactly what is supposed to be there (apart from the 'Our Souls Our Souls Our Souls' bit).
First prove you do actually have it, post a photo of the runout groove and then I'll be happy to do it.
