NYC $1 #571 Precancels

I am going cross-eyed over these.

The single one seems to me to be narrow spaced (9mm) state name, distance to lower line = 1. If it had continuous lines, not bars, it would be: L-5 E var 3. However, it looks to me like it has bars?? Does it - and if so what would it be?

I think the group of 5 is all wide spaced state name(10.5mm), with distance state to lower line = 1.

However, on the top line, the L and R stamps seem to have continuous lines, and the other three in the group appear to have bars??

If that is correct, the L and R would be L-5 E var 1?

The other three would be L-6 E?

I'd appreciate any confirmation / explanation of the single or suggestions as to where I'm going wrong.

Cheers (again).

sometimes precancels with lines [not bars] have lines that do not extend all the way to the edge of the stamp...

this will usually occur at the edge of the precancel device, notice the straight edge bottom left stamp, this is a lines not bars precancel - the line 'ends' at the edge of the sheet.

luckily, there is little value difference riding on the identification

My problem is my dining room is overflowing and I need to dispose ... so if they are all the same type I only want to keep one up and one down.

Do you think I can assume that top center and bottom right are lines (L-5) not bars (L-6), and get rid of one of them?

Is there anything else I should measure / consider to help be certain?

Bottom right is a bars pc.

The "N" of N. Y. does not line up directly under "N" of "NEW" making it an L-5, var. 4.
I have several pairs (vert & hor.) and blocks of 4 that contain L-5, var. 2 and L-5, var. 4.
