Just back from CBC Malaga.
They call it HK1010INA, & it cost $16.00 + GST, walk in price.
It is physically identical to the one from the group buy.
One other thing, when I looked carefully in the Padded Bag from Senol, there was also included a small pillow of PTFE Grease, as attached pics. Probably for pre-lubing the inner of the bearing.
