What Happened to ID-11 Plus?

<p>I was rummaging around in my shop and came across a couple of old envelopes of Ilford's ID-11 Plus. I remember that I used this in the 80s and was quite pleased with it. However, it seems it is no more and there just isn't anything on the web, either.<br>

What is its formula and is there a chemical that can be added to the present ID-11 to get an approximation of ID-11 Plus?</p>

<p>George, I can't recall what the "plus" meant. Ilford seems to be fast and loose with "plus"es and "X"es. ID-11 is pretty much D-76, but I don't know what Plus is.</p>

<p>Google advanced search keyword ID11 plus in the exact wording box resulted in 181 hits with the fifth being<br>

Thanks so much for that link; it has solved most of the problem. I had run across the mentioned ingredient, Cinnamic acid disulfide, in an MSDS sheet. It was listed, in typical devious fashion, as 1-5%. I had balked at accepting the source and the numbers because I was not certain that was what I was really after. Now, because of your link, I can accept it, and make my own. That is assuming, of course, that I can find the chemical.</p>
