Don't we all know that feeling.... It's like finding an old friend again, isn't it?
As for the Dia plates, don't get excited. They're a darkroom product meant for making glass plate transparencies from aerial film negatives by contact printing, so they're analogous to photographic paper. The 'C' in the name indicates that they're colour plates, and they are likely to be a proprietory Agfa process so practically impossible to develop any more. Agfa didn't become compatible with Kodak processes until late in their history, and this product would have used the paper chemistry which become Kodak-compatible much later than film chemistry. 'Dia' only indicates that they're for making diapositives, but from negatives. Direct positive materials were usually marked 'Dia-Direct' or 'Autopositive' depending on the brand. OTOH the glass substrate is a fine, high quality glass with perfectly parallel surfaces ideal for using in an optical path. I know this crap because, as a spotty youth, I worked in an aerial mapping lab.
What life would be without "this crap" is unbearable. Thanks for the additional info.

They, apparently, don't realise that the "Dia" designation probably means that it is positive film. Agfa used to make a 35mm B&W Dia film that produced wonderful pictures. Then again, once I start looking around here I don't know what to spend my money on first. http://www.surplusshed.com/pages/item/i1475.html http://www.surplusshed.com/pages/category/cameralenses_1.html
