3” Metrogon coverage on 4x5?

I have the opportunity to pick up a 3” f/6.3 B&L Metrogon and am wondering if this lens covers 4x5 wide open? If I’ve done the math correctly it looks to be close. I can’t seem to find much info on this 3” version, mostly it’s the 6” that’s been posted about, but my apologies if I’ve overlooked a thread here.

Also, if anyone has photos from this lens, I’d love to see them.

Thanks!

USAF datasheets show that the lens' resolution wide open falls off by more than 50% from center to 45 degrees off axis, i.e., in 4x5's corners. I don't expect it will allow much in the way of movements. Not a tremendously sharp lens wide open, you'll probably not get acceptable image quality in the corners of printing negs taken with it larger than 8x10.

Thanks Dan - do you have a link to the data sheet or can post the relevant section?
I’m not overly concerned with corner sharpness, I’d be shooting it handheld on a Speed Graphic for closeup action shots, so I’m already limited by motion and hand/camera shake. Currently using a 90mm Angulon - I’d like something a little wider, and I do really like the look of photos taken with the 6” Metrogon I’ve seen online.

Incidentally, that link is from a useful list of links that I posted on https://www.largeformatphotography.info/forum/ Go there, then to the lenses subforum. There's a sticky "Where to find ..." The first post in that discussion has a link to the list, which is a pdf with bookmarks that serve as a table of contents. Download it, online pdf readers don't present the bookmarks.
