Silver spurs from an unknown site

In the 1970s or the early 1980s an anonymous donator has gifted a pair of spurs to Zdenko Vinski, who had been in charge of the Mediaeval Department for decades. Unfortunately, the whereabouts of the discovery and the find spot are unknown and we may only speculate that these spurs were found somewhere in former Yugoslavia. They are nonetheless easily identifiable from a typological point of view, being late Roman spurs belonging to the so-called Leuna type. This set may be dated to the 4th century AD. One may presume that this set was found in a grave, since Leuna-type spurs are more often than not either grave finds or finds discovered within Roman military sites and settlements, the latter finds usually not being full sets but single spurs or fragments. The find context is shrouded in mystery because the discovery did not occur under archaeological supervision and within the legal frame of professional field research. One may only conjecture what else could have been found in that grave but in any case, the discoverer, or one of the discoverers, contacted Zdenko Vinski, probably in order to get more information about his (or their) find. The late curator must have somehow convinced the anonymous finder to leave the spurs in the Museum but he probably never managed to obtain more information about the find spot and the archaeological context.
