  We analyze the scalar products of the elliptic Felderhof model introduced by
Foda-Wheeler-Zuparic as an elliptic extension of the trigonometric face-type
Felderhof model by Deguchi-Akutsu. We derive the determinant formula for the
scalar products by applying the Izergin-Korepin technique developed by Wheeler
to investigate the scalar products of integrable lattice models. By combining
the determinant formula for the scalar products with the recently-developed
Izergin-Korepin technique to analyze the wavefunctions, we derive a Cauchy
formula for elliptic Schur functions.
