Fascinating! Your knowledge of arcane Ottoman stuff knows no bounds.
Do you read or speak Turkish?
The sum total of my Ottoman collection is two Gallipoli Stars: one Enamelled German version marked BB&Co, and a painted original Turkish one. I was nearly taken in by a very convincing Ottoman pilots badge a month or two back in ebay, actually placed a bid and was outbid. The same seller posted another very authentic looking one a month later, as these are rare as hen's teeth I can only assume they are quality reproductions.
