Cross processing Agfa CT18 question

I have 4 rolls of Agfa Color CT18, ISO 50. Its a transparency film, dated 1979. Don't know how it was stored.
Thought I would shoot it & cross process it.
Is this a waste of time or can I get some B&W images out of it?

Thanks

Dan

Who can say! Do a clip test.

If it were me I'd cross-process it in C-41. Either way, I'd rate it at 25 or less while shooting.

CT18 was an Agfa transparency process that is now obsolete commercially. I think Agfa changed to E6 process (same as Kodak etc) around the late 1970's early 1980's When they changed the ASA/ Din changed to 100 ASA, 21 Din. (Din 18 = 50 ASA).
I never processed Agfa slide film but I did process Agfa negative film CNS back in the day. I know that if you try to process a CNS film in standard C41 it will melt the emulsion (C41 is 38C while CNS was 20C)
There are threads on here that show people processing CNS in C41 BUT at 20C
The same may apply to the CT18, I don't know.
I did a quick search on CT18 but couldn't find out what temp the dev was at.
If all else fails process as B&W.

Thanks for the info on the processes. I have been leaning towards a B&W process of it
