'Heath Lock'.
Heath Lock, at the junction with the Wakefield Branch of the Aire & Calder Grid Ref: SE 3492 1998 [BAc-001-020] is stated on the card for the print but this does not bear any resemblance to that location. In particular, there are no buildings on the left in this reach and the bottom left of the picture appears to show an approach to a bridge over an arm that did not exist on the reach.
