A bit atypical, but genuine
Too late to add in on my last comment. The "boat" shaped second D was something he did on and off. I'm assuming that's what had you confused.
Always happy to help...."young grasshopper". Lol
All the best
.Yes , it was the "D" what confuses me....you are right...but now its clear. It pops of today at the German Ebay. https://www.ebay.de/itm/225746941847
I think it's good
It’s genuine, albeit a little odd in places.
