Help with identifying this Implant System

[Toto]

Patient needs new rubber rings to line the inside of female part. Any help appreciated re what make this is. I should have taken pic of implants too - they are ball shaped that clicks on to the female.

Looks loike a copy of old OSO Attachments, see Preat corp. I think that may be what they were.
