Vesta ortho film 4x5

[Timefreeze]

Several years ago I bought a pack of Vesta Ortho 4x5 film from the Econozone. Does anyone the iso rating for this film?

Thanks,
John

Why don't you just test it? The chances it's faster than EI25 are small. I'd do a test exposure at EI 25,12,6,and 3. You can use your darkslide to do a quickie test strip on one sheet of film to get in the ballpark.

Thanks for the reply, I will give it a try. John
