What's the length and the diameters at each end of the pin? I've got some
cables for Burroughs patch panels that might be useful.

I thought about machining a ram to deform an existing modern pin (or
even just tubing) to create the taper.
I also tried to cast some out of solder, but they had bubbles and were a
little too soft (tin-lead solder). Also, with a solder connection you
really need a good strain relief. At some point it's too much work for
what you're accomplishing (and still not very authentic).

The photos get a little bigger if you click them. Those bits of stamped
brass or whatever they are made of were probably pennies each.
I've thought about what it might take to manufacture a pair of steel
rollers that could stamp those out but I haven't gotten very far with
it. Same idea for the backplane bus strip DEC used to sell on the
roll.
Depending on level of detail, either a small CNC or possibly a wire
EDM could make the dies.
