Dodgy Precancels

I've been sorting some stamps and I've come across a load of precancels most of them are Boston mass on 3c lincoln's or new York ny's on random stamps but these ones are double prints and almost unreadable except one that seams to me to be a error in the plate it says cufflo n y which at a guess should say buffalo unless buffalo isn't in ny or is there a place called cuffalo if this is a fault is it documented any info on these would be nice

They are:
Buffalo NY L5, Tonawanda NY 512, Minneapolis MN 164, and Middletown CT 552.
They are all sloppy printing but not unusual for these.

What about the buffalo one because that first letter is not a B because its not square at the back

The Buffalo overprint is just a poor impression.

The Minneapolis is clear & normal.

Te other 2 are challenging, nice job Chasa
