  We obtain an AdS$_{2}$ solution to Type IIA supergravity with 4 Poincare
supersymmetries, via non-Abelian T-duality with respect to a freely acting
SL(2,$\mathbf{R}$) isometry group, operating on the
AdS$_3\times$S$^3\times$CY$_2$ solution to Type IIB. That is, non-Abelian
T-duality on AdS$_3$. The dual background obtained fits in the class of
AdS$_2\times$S$^3\times$CY$_2$ solutions to massive Type IIA constructed in
[1]. We propose and study a quiver quantum mechanics dual to this solution that
we interpret as describing the backreaction of the baryon vertex of a D4-D8
brane intersection.
