Help with identifying c-mount lens

[edz]

Hi, I was trying out some c-mount lenses whilst on a trip to Beijing recently but unfortunately I forgot to make a note of their names. I did take a photo of one though - can anyone help me identify the make of this lens? It's c-mount 25mm f1.9. I've had a look at lots of lenses of the same specification on the internet but can't find a picture of one that looks like this. Thanks for any help.

Looks like a Wollensak 25/1.9 to me, but I'm not 100%. It's similar to the Wollensak 25/1.9 Raptar I have, but not quite identical.

Looks like a Kodak Cine Ektar II to me.

Thank you both for your help. It does indeed seem to be a Kodak Cine Ektar II - http://hokkorihokorin.blog26.fc2.com/blog-entry-18.html
