Monchshof Dark Beer Kulmbacher

Hi all: Wondering if anyone remembers or ever had Monchshof Dark beer circa late 1970’s early 80’s. Monchshof brewery was consumed by Kulmbach brewery many years ago and while there are a couple Monchshof styles still brewed this one is not. I always thought it was the best Dunkel from Germany and have always wanted to try to clone it. But I really dont know how to replicate such a flavor. I was not really like any of ther other dark beers of the day except possible Hacker Pschor Munich Dunkel. Anyone that remembers this brew chime in.
