Aufruf - Shabbos Shpinholtz

Yehuda Nathan wrote: Shpinholtz means spinning wheel, which a Kallah normally received as a wedding present from her Chosson's family.

This is the common explanation, and the following is written by Rav Chanoch Erentroi, עיונים בדברי חז"ל ובלשונם:

נשים גם נהגו באותם הימים לטוות ליום החתונה ולכן אומרת הגמרא בגטין פ"ט ע"א שאם מעידים שראו "נשים טוות לאור הנר" זאת אחת הראיות שהיום שם חתונה. בימי הבינים קראו באשכנז לשבת שלפני החתונה "שבת שפינהולץ", עיין מגן אברהם תקנ"א ס"ק ו'.

But there are some other explanations. This is what Hermann Schwab, "A World in Ruins" wrote:

The first festive harbinger of a wedding was the preced­ing Sabbath called Spinholz. The origin of the word is disputed. One explanation, according to which it found its way to the German ghetto from the Italian Jews, traces it back to the Italian 'spinalzare' (to make merry). Others link the word with spinning, an activity which in the Middle Ages constituted a large part of a housewife's work. It may be a reference to the new home awaiting the young wife. Be that as it may, the Spinholz Sabbath was a round of gaiety focused on the betrothed pair. The programme varied in different communities. The Friday evening as well as the Sabbath was taken up with visits to the homes of bride and bridegroom, and merry-making at the dance-house; which no community lacked. The bridegroom would already be wearing his ceremonial Sarbal (festive coat) and Mitron (cap), and the bride, too, would be dressed in festive garments. The ensuing days before the wedding also found the betrothed pair in this attire. The celebrations on the Spin­holz Sabbath were not confined to the home. They were no less manifest in the synagogue, where the bridegroom was the object of special honours and Spinholz-melodies rang out.

Rallis wrote: I have in the instructions for the Kaddish Tiskabal following Shabbos Musaf the following:

שבת שפינהולץ (Aufruf) החזן מנגן 'יהא שלמא' ו'עושה שלום' בניגון חתן וכלה.

In which book of Minhogim is this brought?
