Reproducing a mating thread is not a difficult job. Knowing the pitch and pitch diameter is the easy way to do it. Not knowing those dimensions is not an issue either. The pitch can be measured and determined by the machinist and is most likely the same as other size pullers The pitch diameter can be gauged by feel as the thread is single point cut. Anyway it was just and offer to help, no offence to anyone.
