Perhaps Professor Mahir Banu (Mimar Sinan University) can help? She wrote an article in 1996 on the Mamluk playing cards at the Topkapi,which was published again in 2003:
Mahir, Banu, "Memluk İskambilleri-Topkapı Sarayı Müzesi Kütüphanesi", P (Sanat, Kültür, Antika), Sayı: 1, Bahar '96, İstanbul, s. 40-46.
Mahir, Banu, "Topkapı Sarayı Müzesindeki Memluk İskambilleri", P (Sanat, Kültür, Antika), Sayı: 31, Güz 2003, s.116-125 (ikinci kez yayımlanmıştır)
While that was some time ago, as a Professor at a fine arts university in Istanbul with several theses on Topkapi palace artefacts to her name she still may have contacts or references that may be of help: In case you haven't tried her already - I will pm you a link with her email -
Kwaw
"Memlük İskambil" or "Memlük İskambil Kartları" is the turkish if you want to google search - but it will be 99% rubbish drawing upon western occultist nonsense with a Turkish twist (also - google translate is terrible at translating Turkish!)
ps: I think she speaks Turkish, English & German
