Morphological and spatial analysis proved existence of local variants of fibulas belonging to the middle La Tene scheme with a conical target, which is decorated with a filigree imitation, on a foot that is. This type of jewellery is typical of Celtic material culture in the Carpathian basin of the LTC1 phase. In the text these fibulas are coded as BF-HID. Spatial analysis of the BF-HID fibulas has revealed that there were three 'centres' of their production in the Carpathian basin. Every one of them had characteristic means of expression. One centre was situated near the confluence of Sava and Danube rivers in present-day Serbia, where according to written sources the Scordisci tribal union was located. A local jewellery 'workshop' (workshops) manufactured fibulas with a foot bearing a target that was decorated with an openwork trefoil. Another manufacturing centre of the BF-HID type fibulas was situated in the upper Sava and maybe also Drava basins in today's Slovenia, where ancient annalists located residences of the Taurisci tribal union. Several variants of middle La Tene fibulas with openwork target decorated with pseudo-filigree S-shaped ornaments arranged mostly into a rosette are of local origin. Anyway, workshops in the both centres used to attach decorated targets to fibula foots by welding. Scordisci and Taurisci made these fibulas rather massive with the length of 55 mm and above. The third centre of production of the middle La Tene fibulas with the pseudo-filigree target on its foot has been proved in Transdanubia on the territory of the present-day Fejer comitat in Hungary. A conical target of the BF-HID type fibulas made in Transdanubian workshops had different number of concentric pseudo-filigree fibres. Its top was shaped into a rosette of small bumps - imitation of granulation. Targets of these fibulas were attached to foot with two rivets. The Transdanubian BF-HID type fibulas differ from those made in the Scordisci and Taurisci milieu also by their metric parameters. They were slighter, not longer than 40 mm.
