Hello Lorenzo,
thank you for your comment. Unfortunately, I don't have the medal bar. This decoration come from the family of my father but I have no information on the recipient (on the side of my mother's family it is the opposite, I have the information on the recipient, but I don't have found the medal)
Thank you for your information (and nice picture), I didn't think this medal awarded also the foreigner veterans of the napoleonic's army but it seems logical. I have already seen a certificate for this medal, it is not very scarce (the box is scarce!), but, currently, I don't have picture of this document. The next time I see a certificate, I will post a copy of the document here.
