If you own Ilford PQ Universal or Ilford Multigrade Paper Developer, would you please post the lot number -- something that looks like 80D027 (mine). I have a mystery bottle of Ilford paper developer. When I decanted it to a smaller bottle, I copied down the lot number and threw the packaging out. Now I need to reorder, and I want what I had before. But I don't know if I ordered PQ or Multigrade. It's a strange request, I know. In short, I'm trying to identify the product from what I think is the lot number. Thanks.
