Marklin Trafo 6631 - transformer/controller

I can't remember when or why I acquired this as the only Marklin stuff I ever recall owning was Z gauge! Came across it when looking for something else. Model number is Trafo 6631 and having Googled it dates from the early 90s. It displays signs of wear and age plus the case has a scar where it has come into contact with (I suspect) a soldering iron. I plugged it in to see if it works and it does. I put my test meter on it to show the outputs - all AC. My German is not good, but hopefully you can work out what it's supposed to do from the printing on the faceplate. It has a continental 2 pin plug attached which will mean either using an appropriate adapter or changing for a UK spec one. On the scales it weighs around 2.25kg so using Royal Mail would be expensive. I can send by Hermes within the UK for £7.50. As I have no use for it, so rather than consign it to the bin I thought someone might like it for a fiver.
