So I recently met someone uses this buckle (pics attached), with that being said the closest thing I could find was on another website and a facebook post by SUMP UK. So I got into contact with one of the Sump UK dealers that I know here in the US. With that being said she did not have it. So the searched started.....I got into contact with Sump UK on facebook. Sadly he said the last time he saw them was 4 years ago and that he never made them, He just used them for diving. If anyone knows anything about the whereabouts or finding a person who sells this buckle please let me know.
