Rodenstock grandagon n 90 f6.8

[Pedro_fiz]

Hello.
I am looking for this lens to increase my LF capabilities.
I have found two and one of them is “Sinaron W” the other doesn’t indicate anything.
Are both lenses equivalent? Are both of them useful in a 4x5 graflex crown graphic?
Thank you for your time

The one showing the Sinaron W indication is a Sinar selected one, which probably means that Sinar performed an extra test on the lens. Otherwise it is the same Grandagon N 90mm f6.8. The one i have is an excellent performer.
