TYPE 1 or TYPE II 2 Cent washington 599 or 599a

My eyes are not as great as they were when i was young. Can someone identify this as a 599 or 599a ?

 

The stamp is definitely a 599.

 

I concur with <HOCH>

These identifications require very, very "close" work and make me glad that I don't collect this series, but grateful that we have collectors like Hochstrasse who do and can tell the differences in varieties.

The U.S. Third Bureau is a world unto itself. Too many variables for me. I do notice a many errors in identification result from not correctly using a perforation gauge.

Of all the books and chapters of books devoted to ID'ing these stamps I still like Barbara Mueller's methods in United State Postage Stamps! A true classic of U.S. philatelic literature.

Not my cup-of-tea but I can appreciate the fascination others have with them.
