Rabbi Moses Meir Perels - Need help finding Megillat Sefer (1710)

Need some Hebrew help. Looking for "Megillat Sefer" (Prague, 1710) by Moses Meïr Perles.

Not only do I need to work out some really tough problems in the Pereles tree, but apparently in the foreword to Megillat Sefer he recounts an episode where he was stuck in a winter storm during Purim 1709 in Nußdorf outside of Vienna along with my 6g-grandfather Benet Nachod.

Moses Meïr Perles:
Rabbinical author; born at Prague 1666; died there March 30, 1739. In the beginning of the eighteenth century he lived at Vienna in the house of Samson Wertheimer, for whom he acted as private secretary and almoner and by whom he was supported even after he had returned to Prague. He wrote "Megillat Sefer" (Prague, 1710), a commentary on the Book of Esther based especially on Rashi's commentary on the same book. In the introduction to this commentary he mentions the following works written by him: "Pene Ḥammah," homilies on the Talmudic haggadot; "Or 'Olam," sermons for the holy days; and "Ḳiryat Arba'," sermons for the four special Sabbaths (see Parashiyyot, The Four). The inscription on his tombstone mentions another book of his, entitled "Me'ir Netibot," which may be identical with "Or 'Olam," the latter title not being mentioned there.

Perles was related to many prominent rabbinical families, about which he gives very valuable (though not always correct) information in the preface to his "Megillat Sefer." Similar information is found also on the fly-leaf of the manuscript of "Naḥalat Abot," a commentary on Pirḳe Abot, now in the Bodleian Library. This work was written either by Perles' great-grandfather Eleazar or by the latter's father-in-law, Isaac ben Jekuthiel ha-Kohen, who was a rival of Löw ben Bezaleel.
