Hello to all. I am reviewing several of my 3 cent stamps hoping to extend my knowledge. I came across the item below which contains a line connecting the upper right triangle to the upper right diamond block. I would like to know if this a distinguishing characteristic of a specific plate position or if there are several positions that have this added line.
The magnified photo notes 22L1(L)but this is may be incorrect. The second photo is the full stamp.


Thanks for any input.
