Hardinge or any other second op lathe would make this an easy job .
I'm using a manual lathe (South bend9A) with collets. Should still be fairly easy?

I have a Z axis DRO. Which one of their tools would you choose? I've made parts with just a parting blade (light cuts) similar to the seco tool inserts and it has worked fairly well except the finish is sometimes not great.If you have a manual lathe with DRO then I would use a Seco MDT tool or equivalent and turn the whole thing in one hit with the same tool. Cut the bar into 20" lengths that will fit inside the lathe headstock withot protruding making 19 pieces per length. You should be able to hit under 4 mins per piece. Knock the sharp corners off before parting.
I think 2 or 3 seconds on a 120 year old screw machine is ridiculous.

Same collet size? How? Wouldn't I need a 3/8, flip the part and then a 1/4" ?Buy 100 1.250" sticks. You could use the same collet size for the whole operation. I think 7 min is very doable.
I use a 3mm wide insert most of the time. When I spoke to the Seco Engineer he told me the trailing clearance was achieved by a small deflection of the blade when traversing, this helps with the finish.I have a Z axis DRO.
