Could you please guess "my nub"?

Thanks everybody!

No on the other pictures there is no nub showing at all!

Here I will add them..

And this one..

If I look closely at my scan picture, I see a little second line (or more ending) below the "end" of the nub. So nothing above it, but something below it at the end. Isn't that a good sign?

Almost like a tiny fork at the end. Also at the beginning I see very a light a very short line above and below the nub. Would that mean anything?
