I've just learned this is actually a re-post.
However, the reason it didn't show up on my search is that I have a model name for it which didn't appear anywhere in the original puzzle thread.
In that case I'll leave it where it is and whoever can add this model name will get a point before I merge it.
It does mean I can't promote it to the Pro's however, so if no-one gets it I'll simply end up merging it.
