matrix number is tricky to read but looks like its correct 66-3002. The only other label shot I have found is on Discogs & it differs. Saying that the Discogs version looks slightly tatty round the rim. My cable is clean on a raised edge like other Mirwood issues.

Your copy doesn't look quite right to me- the 

font is different. Might be from another pressing

plant though ?? 

Original from different plant.

Don't know all the ins and outs but deffo different demos of "Stubborn Heart" on Mirwood.

Most likely others too.
