The copper alloy fibula type Zachow was discovered in autumn of 2006 at Pręgowo Dolne, near Kolbudy, distr. Gdańsk, in a local field. This rarely recorded form belongs to the group of fibulae with wings (Flügelnadelfibeln), classified to the relatively large family of plate fibulae (Plattenfibeln). Except for our specimen, at least twelve fibulae type Zachow is known, the majority of which came from area of the Jastorf Culture in Hither Pomerania (Vorpommern), Mecklenburg and Western Pomerania; one fibula was found at Gröstorp, Scania. It is interesting that both the latter specimen and the brooch from Pręgowo Dolne are nearly identical and differ in some respect from all the other finds of type Zachow. What is meant here is the form of their trumpet-shaped head, the decorative motif of concentric rings and details of the construction of the catch. In contrast to other fibulae of this type, specimens from Gröstorp and Pręgowo Dolne have the eye to fasten the pin and the catchplate outside the central plate, under the head and the foot respectively. Dating type Zachow fibulae is extremely difficult. Nearly all of them are stray finds or come from assemblages without chronologically diagnostic forms. Even so, the accepted view is that they are the latest form of Plattenfibeln and were in use at the end of the Older Pre-Roman Period (ältere vorrömische Eisenzeit). We have no grounds to date the specimens from Gröstorp and Pręgowo Dolne differently.
