					<para>
   We present radio observations at 6 cm for 93 ACO clusters, in which the
   brightest member consists of either two galaxies of roughly equal
   brightness inside a common halo (a dumbbell) or has multiple nuclei. A
   subsample of 27 dumbbell systems, belonging to a volume-limited sample, was
   observed with the VLA and ATCA. The remaining clusters were mapped with the
   VLA. The detection rate in the volume-limited sample is 44%. In all 93
   clusters observed 43 brightest cluster members were detected in the radio.
   Parameters are presented for all the radio sources detected in the cluster
   fields.</para></abstract>

         A367:  there is a very faint (2 sigma) radio source right at the
                 position of the galaxy.
         A1791: the radio source is complex, and the galaxy is almost certainly
                 associated with the source.
         A2854: there is little doubt that the dumbbell system and the radio
                 source are associated, even though the positional coincidence
                 is difficult to judge, due to the absence of a strong,
                 well-defined radio core.
         A3150: there are three galaxies close to the radio source. This is the
                 only unclear case in the whole sample. The identification
                 should be considered uncertain.
         A3151: one galaxy falls right inside the double radio source, so the
                 identification is probably correct.
         A3391: the radio source is complex; a faint core is present and lies
                 close (~5 arcsec) to the eastern galaxy of the dumbbell system,
                 and we therefore consider the radio source associated with this
                 galaxy.
         A3432: see "Post-Publication Notes"
         A3532: similar to the case of A1791: one galaxy is in between the two
                 lobes of a double source. The identification is quite likely
                 correct.
         A3618: the western galaxy is probably the one associated with the radio
                 source.
         A3706: the radio identification is uncertain due to the very faint
                 radio source associated.

                 position of the galaxy.
         A1791: the radio source is complex, and the galaxy is almost certainly
                 associated with the source.
         A2854: there is little doubt that the dumbbell system and the radio
                 source are associated, even though the positional coincidence
                 is difficult to judge, due to the absence of a strong,
                 well-defined radio core.
         A3150: there are three galaxies close to the radio source. This is the
                 only unclear case in the whole sample. The identification
                 should be considered uncertain.
         A3151: one galaxy falls right inside the double radio source, so the
                 identification is probably correct.
         A3391: the radio source is complex; a faint core is present and lies
                 close (~5 arcsec) to the eastern galaxy of the dumbbell system,
                 and we therefore consider the radio source associated with this
                 galaxy.
         A3432: see "Post-Publication Notes"
         A3532: similar to the case of A1791: one galaxy is in between the two
                 lobes of a double source. The identification is quite likely
                 correct.
         A3618: the western galaxy is probably the one associated with the radio
                 source.
         A3706: the radio identification is uncertain due to the very faint
                 radio source associated.

      "I had no time to directly check on the map (I am teaching), but from my
