What carrier for this bucket?

Trying to figure out what this bucket fits. Note the bucket is upside down in the picture. Anyone recognize this bucket attachment and know what it fits? It is not a skid steer or a JD Quick Attach. Thanks for any help

JRB type coupler -- I think. Used on wheel loaders and ????

That close together of mount plates looks like a telehandler attachment.
