Just for context, I purchased a collection, and I'm breaking it down. This stamp was highlighted in the auction listing as a 20. What I thought I saw was that the the visible balls as the bottom looked rather complete. That didn't seem right for type ii, but I hesitated to say type i. It appears I was on the right track, I need to be vigilant with this lot. You guys are great and very appreciated.
The top ornaments and secret mark in medallion oval together point to Plate 12 Relief B or C, and you are right, rlsny, that the bottom right ornaments are too complete for Relief B, hence Relief C (Type I).
