I did a shaalas tinok on the Daled of echad, he could not identify which letter it was, even after correctly identifying a regular daled as well as a large echad daled in another mezuza.
Is there a sevoro to say that tinok would not apply for the large daled?

Looks like the metayeg botched the tug on the hay. Fortunately it did not go into the space of the chof pshutah but I'm a little worried about what it's done to the hay since its all connected. I think though, it's too thin and negligible to cause a shinuy tzurah of the hay.
