Hi 922F,
I did additional research
The medal had 6 models
The medal you listed appear to be 3rd or 4th model
The difference is the size the 3rd model is 37 mm 4th Model is 30 mm
The ribbon is unknown The medals came with or without ribbon loop
The two desk top medals i listed appear to be with the features of the 5th and 6th model
The Gilded one is 64 x47 mm 100.33 grams It is made from heavily gilded Bronze
There is a variation of this size in silver - 69.33 grams
the silver one that I have and listed is the smaller variation 35 x 45 mm - 30.33 grams
The Gold medal is smaller size still unknown to me - 14 grams
This is the gold Variant 14 grams
