Taylor-Hobson 10 1/2 inch is covering how much?

[Grayhand]

I have a old Taylor-Hobson Cooke Portrait Anastigmat 10 1/2 inch, Serie llB, f4.5
Serial# 202139

Considering to sell it, but I would prefer to give correct info about the lens.
Normally reduce the amount of interesting discussions after the sale..

If I under stand it right, this lens covers 4x5 and also 5x7 good, but heavy vingeting on 8x10?

Grateful for any information

Up to full plate ( 6.5x8.5").

That is what was listed in the catalogs but, I have this lens. It covers 8x10 with room for small movements. So in other words, no vignetting.

It's a lovely lens but is the aperture broken or is that just a not so good picture (#4). Looks like it was sold originally in the French market. Flou ~ Artistique. First I've seen inscribed that way.
