Actually, 144 quid for an MC isn't bad (Red MC or just regular?)
The 'Olympia' version was the original, it's got a gajillion blades, you can tell them apart easily because of the shape, the tripod ring, the aperture see through a hole etc.
I'm not sure if the glass was recalculated between that and the other version, but the rest of them look about the same shape (physically, at least).
I've got a Zebra version and a Red MC. The zebra I have to sell one of these days (it's got slight fungus on front element that doesn't affect the photo).
I'd share samples, but they're all bad scans that need redoing, and the rest are digital (I took some great shots of a concert from the back of the room with it)
My impression?
I love mine!
Big!
Excellent portrait lens.

A beautiful, painterly rendering without being soft.

Must be very careful with focus at f2.8.
Did I say Big?
Awesome bokeh.
Use a tripod and you will be happy.
Carry it in a backpack, not around your neck.
Because its big and heavy!!
Couldn't have said it better.
BIG!
Buy a tripod or start lifting weights!
