Ok, I thought so. It is good to know that it's something at least standard (though old).

I have NO IDEA as to the workings of either E-3 or E-4; is it possible to process this manually (either with the correct chems. or perhaps in a modified E-6 / C-41 process)? I'm not necessarily looking for quality; I just want to get some images off of this.

Ideas anyone?
