Don, then you need to write one! There are, I think, about 4 books out there on Parkers, each one containing information that the other does not, and in some cases correcting misinformation. I think most folks consider the most recent one (the multivolume one) to be the best of the bunch. But I'll bet someone, somewhere, has found a mistake or two.
It's difficult to be totally "comprehensive" in a magazine article about a particular gun model, even one as recent as the 101--which had, compared to some other models, a relatively short production life.
