Rabbi Greenfeld from Vaad Mishmereth Stam published an article showing that the letter פ can be written in the "right shape" and can be written in a "wrong shape" which was invented by a Sofer from Minsk. The title of the article is pretty harsh:
זיופי הסופר רא"ח שמאלעוויצער ממינסק
Here is the link:
And here is the article in larger format (easier to read):
There is reference to משיכה לאחור which is valid with ancient sources, and reference to a "broken פ " which is invalid. I could not understand the difference. Can somebody please explain?
the "right" shape or the "wrong" shape?
