A2-5 or A1-5 Lathe Spindle nose specs

[md63825]

Does anyone have or know where I could find the dimensions for an A2-5 or A1-5 lathe spindle nose. I need to make a custom chuck and I want to attach it directly to the spindle. I could reverse engineer it but I was hoping someone might be able to provide the information so I don't have to go to all the trouble.
