I see that there are many different minhagim with the taging of the letter Chet.
1. There are some who write only a Makel at the very left of the left Zayin.(Pic 19)
2. Some who omit the Makel and write a tag between the middle and left of the left Zayin(Pic 20)
3. And there are some who do both of the above. (Pic 21)
Input/sources greatly appreciated! Thanks.
