8HP50 Alpina flash? Is there such a thing?

[noname]

Looking online I see people refer to a 8HP50 Alpina flash but can't see an Alpina with a 8HP50 fitted as they seemed to opt for the stronger 8HP70. Am I chasing rainbows looking for a type code for a Alpine equipped with a 8HP50? Can anyone advise? Thank you in advance.
