A new low frequency radio selected Sample of 125 Quasars complete down to 100 mJy at 408 MHz is presented in this paper. The sample is a part of the B3-VLA sample: 1050 radiosources selected from the B3 catalogue at 408 MHz and observed at the VLA (1465 MHz, C and A configurations). Out of the 352 sources, identified on the POSS-I down to tex2html_wrap_inline1312, 172 are quasar candidates. In this paper we give the final assessment of the quasar sample from spectroscopic observations of the candidates. The final complete quasar sample consists of 125 objects. Furthermore 3 Bl Lac objects have been identified and two Bl Lac candidates.
