I’m not sure but this one may still be available.

I actually just purchased the exact glovers donkey you posted this spring! I am using it to complete a couple of pairs of gloves that I started making a year ago! (A Christmas present never completed )
I am finding it a bit difficult to keep the leather seams on the fingers to line up and stay perfect before I get them clamped to stitch them. Any recommendations?
