It's my understanding that later model len's have two rows / lines of lettering one above the other. The original 73 len's have only one line of lettering.
My questons are 1. How much are the single line len's worth? 2. How much are the len's with none /not any markings on them worth?
For clarifacation.. when I say "above the other" I'm not talking about one line at top of lens and one at bottom. I'm saying there are two lines at the top (there is also lines at the bottom).
I have one lens that has one line at top of lens that reads V.E.M. OK-1 SAE D6 and one line at bottom of lens that reads MADE IN USA. Is this an original lens? I also have two lens that have no markings anywhere.
