12" Wollensak question

I just purchased a Barrell Wollensak 12" f6.3 Series IV Velostigmat on Ebay
heres the auction
does anyone have any idea the coverage (image circle) of this lens?
Im curious as to whether it can be used for 8x10 or possibly larger?

thanks in advance.

PS I did a search and didnt find any relevant threads/posts.

According to "A Lens Collector's Vade Mecum", the Series IV f/6.3 Velostigmat lenses were made in focal lengths from 3.5" to 12" and had 60 degrees of coverage. You should be fine with 8X10.
