Notch Code verification, please

Received some used 4x5 film holders yesterday, and one of 'em still had two sheets of film in it.

I've looked online for a code, but couldn't find anything definite. My best guess is the old code for Ilford FP4+.

I just want a double-check before I dunk it.

Could be FP4 (not Plus.) FP4+ has a smaller semi-circle notch just to the right of the left-most notch in your diagram.

Just looked it up. It's old FP4+; new is identified as I described above.

Thanks for the back-up. Getting soup up to temp now.

Dunno if it's even been exposed. If it has, maybe I'll see something. If not, I'll have some practice sheets.

Developed for 8:00 at 72°F with Ilford DD-X at 1:4, got two shots of a sleeping baby. Hanging to dry now.
