Need Help Again For Those Precancel Types

Hello,

the last weeks I collected some new questions for this forum here for precancels which I find interesting and / or I am not sure about the type:

1 Anaheim and 2 Fort Atkinson: no precancels?
3 Des Moines: L-8 R seems the closest?
4 Brockport: I asked already about this, and you told me L-4 TS, chasa, but when I check the L-4 TS should have lines 7mm apart, but on this stamps they are 12.5mm apart, so it can't be this type?
5 Milwaukee: L-4 TS?
6 Greeley: PSS 526? (Nice double precancel.)

looking forward to learning on them.

my guesses - Anaheim, not a precancel
Fort Atkinson PSS-713
Brockport L-2 - footnote-4 line spacing varies on the plate (I was wrong about L-4)
others OK

hello chasa and thank you again.

Anaheim: any chance in such a case to verify if it's a precancel or not?

Des Moines: L-8 is not really exactly the same, do you have similar examples, or is there also spacing varieties? (the L-8 normally looks more condensed vertically?)
