Hi,

I have a Anscow View with a Goerz Dagor f6.8 Series II No. 6 12 inch lens
Since the Tintype needs a lot of lighting, I'm thinking of upgrading my lens to a 5.6

What do you think of this lens:

Do you think it is indeed an easy fix, or there no way to tell and I'm taking a risk buying it?

Thank you for your feedback!
