938g quick coupler

Hello I have a cat 938g with a quick coupler I have cat forks for it and an unmarked 4in1 bucket for it I would like to find a 4+ yard bucket for it but can’t figure out what coupler is on it. It looks like a balderson but measures out wider and taller than a balderson. I’ve included a picture of what the hooks on bucket look like the tag on the forks the tag on the coupler and measurements from top of hook to bottom hole and from top hook outside to outside any help would be much appreciated thanks
