Please help identify this dryglove system

[Zef]

I have a friend who can no longer dive due to a medical condition. He is selling his gear but he has a conundrum...he has a dryglove system that he does not recall the make/model of.

His drysuit is BARE tri-lam suit that is a handful of years old. The glove system looks similar to the Diving Concepts ring system but I shared these pictures with another forum member who has a set of the DC system and he noted some differences between the two.

Is there anyone here who can identify this system by these pictures:

Any know whether or not these are the old Skanna ring system?

Looks like Diving Concepts rings.

Those are diving concepts rings which changed (very) slightly over the years. They have been out of business a few years now.
