My new gaunts just arrived! I commissioned these from Andrey Galevskiy (Ukraine). I sent him my measurements, and ordered them in Stainless, because I really hate cleaning rust off of gauntlets, with all their little bits and pieces.
It's slightly a mixed bag. I won't want to use these for Blossfechten (unarmored combat), because the thumb is actually pretty immobile. Also, there's a large gap that opens up between the glove and the finger portions of the steel (as shown below). The secondary knuckle plate moves really nicely though.
However, for Harnessfechten I think they'll be fine. That's mostly either pole weapons or half-swording anyway, so the finger mobility isn't as much of a concern. This all works works out OK since I ordered these primarily for fleshing out the 14th century kit a bit more anyway.
The gloves appear to be a linen canvas sort of material. The thumb is a little confining length-wise, but in making a fist it's not too bad.
I think part of the problem with the gap opening is that the gauntlet is just sitting too far forward, because of the thumb length, and some of the side stitching. At some point I may want to redo the stitching and reposition the thumb a little, and that might solve some of it. The stitching looks easy. The thumb would entail taking out a couple of rivets on each, and replacing them.
