Countermarked Grosso of Ragusa

I posted this coin several days ago. As I've read it's countermarked and it had been used in the city of Riga. Do you know any catalogue or book where it might be mentioned? I want more information about this coin and countermarks.

I don't have this book, but I suspect it would be mentioned here:
