[LargeFormat] Wolley Ex W 6.25" f12.5 series III 8x10

[Les Newcomer]

I finally got around to fixing this lens I got in a box lot of other 
neat stuff.

I've noticed that the iris is limited to f12.5 but the glass is much 
larger than that.

I was wondering what part of life as I or the lens knows it would come 
to an end if I removed the stop and allowed the iris to open up to it's 
full potiential?

While I understand anything less that 12.5 will not give desireable 
sharpness,

but it might be a whole lot easier to focus........unless there's a 
focus shift when you stop down on this lens.

Any body have any experience with this one?
