First you’ll have to work out what it is from the code to the right. Pre-production disc, with no label, box etc, but content is the same as the bought one. Identify it in comments and indicate that you want it. Australian postal addresses only.
Oh, if you want to identify it without claiming it for the extremely modest bragging rights available from this blog, then that’s okay too. After all, you might already have the disc. In that case, the next one to ask for it gets it.
