So nice to know there is a definitive answer that everyone agrees on 
Vinny, steel grades are still a bit of a mystery to me but I believe it is 1030 (sure everyone's going to tell me I did the wrong thing here...)
Had a bit of a setback today, on close inspection of the internal acme thread I discovered that I now have a nice bronze paperweight. The thread form is weird on one side, I think my boring bar must have rotated in the toolpost part way through the threading job. The back side of the thread has two distinct angles to it, my friend with the mill spotted it straight away when I took it to his place to mill the external shape of the nut. Will probably have to wait til next week to make another, glad I'm not relying on this for a living- or paying myself by the hour for it. On the positive side, my friend has some tapered reamers and pins- good man to know!
