Was just conversing with another fellow about these connectors for an old HP
counter. He found an alternative solution to work in a pinch:

was at Halted Surplus and they had the connector, so I picked one up and
went around the store trying to find something that fit and found
these. I drilled out the holes a little more, spread the Molex pins a
bit, and soldered them to the AC line after pushing the wires through
the shell.
