It's not real leather. It's a fake synthetic leather sometimes called "PU Leather" or "Polyurethane Leather". The photos you already have are sufficient, and to my knowledge represent all the case designs provided by HP for the 49g+ and 50g. The 49G did not have a soft case; it was shipped with a hard plastic slipcover. Production models of the 49G had a light blue translucent plastic cover and prototype models had a dark blue translucent plastic cover.

The slip cases used in the later Voyager models, such as the "smooth" and "grainy" ones you already listed, are also made of PU leather.

I have examples of all of the above cases that have started disintegrating, as PU "leather" tends to do after a decade or so. The synthetic leather-like coating debonds from the fabric base.

Also, while not specified as leather or not in your document, I'm pretty sure all the later leather-like Pioneer cases are PU leather as well but I can't confirm that.

Finally, there is one case you have not yet listed. The 15c Collector's Edition has yet another case design, which is also PU leather but is even more grainy than the earlier "grainy" one you have already listed and also somewhat thinner. I don't know if this case is used on any other models. I have photographed it here: https://commerce.hpcalc.org/images/15c-c...medium.jpg
