Re- question above (1751) on pointing a finger towards the Sefer Torah during hagbaha, some questions.
Q. If you don't see the front of the Torah, but since the parchment is thin (sh'lil) and the writing can be seen from the back side, do you still point and say Vezot Hatorah?
A. Mishna Berura (134: 12) indeed rules that one should not say the psukim of Vezos Hatorah (this is the Torah... ) unless one faces the writing on the Sefer Torah.
Horav Shlomo Miller's Shlit'a opinion is that being able to see the writing from the other side of the translucent klaf and even being able to read some of it (in reverse), does not qualify for the facing-the-writing requirement, since most people would not be able to see what the writing says.
