This looks like C.pellucidum ARM.1169 Grootberg. It is not SB.628 which is ssp. neohallii Deurdrift.

I agree this plant is not SB 628. I posted photos of my SB 628 on 9th November 2013. This year my SB 628 had more pink in the flowers. I will post photos soon. Unfortunately this plant has no collection details.
