Hello Mario! Again, so sorry you had to wait forever to be approved as a member. I hope my apology doesn't ring hollow to you.
I would be very interested in any discoveries you may have made regarding Goetz Meissen pieces. I have had several suspicions that he produced in limited scope using porcelain.
These suspicions were born from my discovery of a hidden drawer contained with Karl's personal medal cabinet that I purchased from the Goetz family in Munich.
This box contained many small treasures of wax seals, coins, plaster casts of medals likely from museums that were used as reference for his creative process. There were also two designs in plaster that match Meissen issued pieces. Florian Goetz, Karl's grandson, gifted me with another unissued piece that was half completed by Karl.
If you'd like, I can create a 'Porcelain' sub-forum for futher discussions. Just let me know! Henry
