A rare book in Ottoman language on the modern geomagnetism and the use of binnacle was published in 1883 in Istanbul. The books includes instructions, calculations and charts. A volvelle, composed of two parts, with attached instructions, which is usually missing, was meant to be cut out and applied to an instrument.
The author, the military commander Mehmed Bey from Aksaray, is not to be confused with the 16th century naval commander Aksaraylı Piri Mehmed Paşa (also wrongly attributed by Özege).
We could only find one institutional example (NYU Libraries, Elmer Holmes Bobst Library). The other examples, listed on Worldcat appear to be eBooks or microfilms.
