56 Packard terminals 14-16ga.

I've only seen the male terminals sold as 56 series.
Those look like they are made from thicker material than some of the females shown above.
You'll have to experiment to figure out which crimp position and tool works for the heavier gage metal.
There's others here who know much more about crimping than me.
Maybe talk to Mr Heater Box, or Bill Evans, or the people at M&H.
