Anyone have instructions for the DensiKit?

Hi, new guy on board.

I have a little kit (called "DensiKit") for establishing a very personalized method of rating the ISO of a given film & the best exposure process. I had used it many times in the past & really liked the standards it set for me. I just found the kit & all components BUT the instruction book is missing. My notes show I used it back in 1992. Getting back into B&W darkroom in my declining feeble years now.

Does anyone have a copy they might be willing to scan & send. I'd sure appreciate it. Can't find any references on line.

Thank you so much.
