  This is a successive paper of arXiv:1909.11492. We prove an equivalence
between the category of finite-dimensional representations of degenerate
supergroup $\underline{GL}(M|N)$ and the category of $(GL_M(O) \ltimes U_{M,
N}(F), \chi_{M, N})$-equivariant D-modules on $Gr_{N}$. We also prove that we
can realize the category of finite-dimensional representations of degenerate
supergroup $\underline{GL}(M|N)$ as a category of D-modules on the mirabolic
subgroup $Mir_L(F)$ with certain equivariant conditions for any $L$ bigger than
$N$ and $M$.
