The Kodak 203mm f7.7 Ektar lens has a lot of people singing its praises. The weight is light enough to carry into the field, and the lens is very sharp, and very inexpensive for a LF lens.

My question is how does one differentiate between the uncoated and coated versions of this lens? Does the shutter or serial number give any clues? Is there a way to tell by looking at the reflections inside the lens? Any inf o appreciated.
