Identifying A Washington A157 595 And A Unusual 606

Hi everyone;
I'm kinda stumped in Identifying these stamps I have 10 stamps I think they are 595's
All are size 11 perf's they range in different lengths and width .
I thought they could be a 554 but the 554 dimensions are different.
The book says a 554 is "18 1/2- 19x22" flat plate
The book says a 595 is "19 3/4x 22 1/4" rotary
I have a lot 19 1/4 and 22 1/2 or 22 1/4 or 19 1/4
It sounds like there could be a estimate of sizes in the book,so what is right ?
I also have a interesting stamp that I think is a 606 its perf is a 10.
I like the marking on the face, I think it's a scratch ,cracked plate or something any idea's?
The first stamp is 19 1/4x 19 1/4 "594"
The second stamp is a 22 1/2x 19 1/4 "594"
The third is the "606" I think.
Thanks You
Dan

Your 595 appears to be 634
Your 606 appears to be 583

Thank You jogil

This looks to be a pretty interesting stamp a lot of variations .
It has four different shades of reds with the many types are I ,II and the 6 different type's of perf's
Many dimensions or size's maybe due to being a made with rotary machine , when you make a rotary stamp it will stretch out the paper some what ,so that's maybe the reason of size problem inconsistent stretching I'm guessing.

Im sorry for the few days of delay I really had to study these 10 stamps to see were I was going wrong with these stamps.
I figured I would see if the measurements were right and they were .
I assumed the perforations size was right but they were wrong I tried a different perforation card and sure enough that first card one was wrong or I couldn't see it right.
So anyway I have only 3 stamps ,jogil was right they are a 634 .
Now I see they might have some value if I could figure what type they are I or II.
Im thinking the first one was a type II and the other are type I, might be wrong.
Here are a couple of pic's
