Brown c41 base?

Seems that it was a product of the old Ilford Imaging, and was similar to Kodak Duraflex.

See pages 128-132 of this archived catalog: http://www.tmax100.com/photo/pdf/ilford.pdf

It is "parked" on tmax100.com - a very interesting site courtesy of a Norwegian Photographer, Eric Hattrem.

Wow! Thank you for this info!!! According to the description, what I have is not Ilford paper, then, as the emulsion is green and the paper is metallic. Someone must have just put the paper in the next available box Oh well... 20x24 metallic paper, basically free... pffft
