I agree with you on the smooth jaws, I sell 20 serrated jaws to one set of the smooth jaws and offer smooth jaws in all sizes. I do not like the serrated jaws on my vises, working in a machine shop we can not have bench vises with serrations. On a quality vise the smooth jaws hold work just fine. I can see in a blacksmith shop the serrations would be needed.
As for the nuts, I agree with you. The Chas Parker ones might be a little tougher to make since some of the smaller vises are a double lead thread, 5/8:3 double lead, making it look like a 5/8:6, they did this to move the Dynamic jaw quickly. If they were to be made I would agree using aluminum bronze material would be the best but the whole slider assembly would have to be made the Aluminum Bronze. In two years I have been asked maybe once for a nut for the larger Chas Parker vises, the smaller ones I've had replacements in stock. I wish I could make the nuts for all the spindle's in these vises but there is really nut much of a market. If anyone needs a square or acme nut then I would look HERE and purchase the shortest length and hand fab or weld on to your existing nut slider. Maybe I should purchase a few popular threaded blanks and offer them as a replacement, but they would be steel.
Grimly, some of the older vises like the Chas Parkers and Reeds did have the jaw faces hand filed but not very deep. Notice the Parker jaws are soft material and can still be hand filed if the owner wants serrations, I build my serrated jaws with a 1/6 deeper counter bore so down the road the owner can machine or surface grind the faces smooth.
