Your machine looks to have the makers reg plate on the front, if so ,with typical German efficiency that should tell you not only the year it was made but also the month and day
The first one I had took 1d and had the playfield converted to 1d payouts which I think look a little plain. The one I have now is on 1d but I have returned it to the original Pf numbers on the playfield and info cards and I think it looks much better that way. You can see the difference in TF's video and the photo above it. However, if you do wish to use the UK coin markers I am happy to send you the kit I made myself (see below). The last photo is how it was when I got it.
