Sacpfeife / Sacpfeiffe (f)
(with) definite article: dieSacpfeife: ➺ Polnische Sacpfeife; Sacpfeiffe: Dubious spelling in O'Neill; NB: Oddly, the spelling also occurs in Stainer, but attemps to search for it in text of the internet versions failed; Even though I discovered it in the Google books version, the only result proved to be Sackpfeife [sic] (➺ p.39!), whereas the spelling Sacpfeife can be found on the 1st page of Chapter VII (p.[118]) ! Moreover, in the Archive.org version the common spelling (Sackpfeife) is mentioned in the identical context (➺ p.[145]).
