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 
,
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.
