This book is the Purim book, written by Rabbi Judah Potok, originally from Leipzig, who was living in Manchester during the war. The author starts with thanks to Mr. and Mrs. Louis Fidler, who made a generous donation towards its printing (at the Narodiczky press in London) and then follows with an illustrious and interesting list of Haskamas (approbations) from:
Dayan Yechezkel Abramsky- Rabbi David Feldman of the Machzikei Hadas in London, once a Rabbi in Leipzig
- Rabbi Moshe Yitzchak Segal, Rosh Yeshiva of Manchester
- Rabbi Moshe Eliyahu Rogosnitzky of Cardiff, previously of Leipzig (I bought my copy from M. Rogosnitzky, Hebrew Bookseller)
- Rabbi Moshe Eliezer Rabbinowitz of Sunderland
- Dayan Samuel Joseph Rabinow of Antwerp
- Rabbi Shem Tov Gaguine, head of the Sephardi Medrash Heshaim in LondonAnd then, of interest to the genealogist, is this page:
And here is the table of contents, which makes you really want to read the sefer – BUT – as of yet I have only found two copies apart from my own, one in the New York Public Library, and one for sale from a book dealer.

Worldcat is showing two copies in California, one at the University of California and one at UCLA. It would be good to have this digitized and made more widely accessible.
