Hmmm. Doctor Mahir confirms the catalog number but places the cards in the Topkapı Palace Museum Library Y. Y.1066.
I've tried searching the online databases using that catalog number and haven't found anything. I think the cards are likely considered objects rather than manuscripts or books. OR the cards simply aren't in the database. The catalog number given most closely resembles the numbers used in the manuscripts database. I did a manual search for the object by selecting all items in the manuscripts database and then navigating to the appropriate location. There is a TSMK Y. 1049 and a TSMK Y. 1084. The cards would fit in to the gap under the designation TSMK Y. 1066 but there's no record in the database.
I've re-sent my request for images (per the instructions on the Topkapi website for research services) using the provided reference/catalog numbers. Hopefully I will receive a response this time.
