We consider the gauged model of Siegel type chiral boson with a Lorentz\nnon-covariant mass-like term for the gauge fields which is found to be\nequivalent to the chiral Schwinger model with Faddeevian anomaly when it is\ndescribed in terms of Floreanini-Jackiw type chiral boson. We carry out the\nquantization of gauge non-invariant version this model in both the Lagrangian\nand Hamiltonian formulation. The quantization of the gauge-invariant version of\nthis model in the extended phase space also has been carried out in the\nLagrangian formulation. The gauge-invariant version of this model in the\nextended phase space is found to map onto the physical phase space with the\nappropriate gauge fixing condition. BRST symmetry associated with this model\nhas been studied with different gauge fixing terms. It has been shown that the\nsame model shows off-shell as well as on-shell BRST invariance depending on the\nchoice of gauge fixing term.\n
