I didn't bother trying to search through my archives since I am almost sure I don't have these files any more. But you remind me to store old versions for purposes like this. Time to start with it!
That being said, I used the powerful Wayback Machine and got the old files from Nov 2016 like that. They are attached below. Please note that the mod still used separate files back then, pk_anim1 for normal gloves and pk_anim2 for black gloves. Those were the days!
