This is the THULE model TH9512 foot for 15cm rain gutters, compatible with professional carrier bars, WingBars, and other Rapid models from THULE. I purchased it new for a Golf 2, but it has been stored without ever being used. It is sold online for around 20,000 yen. Although the box is not included, I will provide a printed copy of the instruction manual downloaded from the internet. Thank you.
