Been a bit busy with life so please excuse my delay, I believe these pieces that you both (Alpha and Obi) own are French or Swiss. The reason is fairly simple, the piece we are refering to as Belgian from Car and Muhic, the Pires is not Pires. From talking to a couple friends here that collect Belgium orders/medals, is that Pires never made Serbian orders/medals so this could have been sold by him or the box was added later for the book's version. On top of this the same icon St. Sava as from the book, I'm fortunate to own two a 5th (sold by Alpha thank you again my friend) and a 4th class. I did a thread on them here, the 4th class has a clear French punch mark, so we can safley assume these types of St. Sava's are French. For both your pieces I would likley assume them being eiher French or Swiss. Hopefully we can obtain ones like yours with punch marks, hallmarks or similar to say for certain.
