I have one of these lenses and it will just about make it on an 8x10. You will have little if any room for movements however. Currently, I use it on my Speed Graphic, and on my View camera for wet plate work. And if the pictures dont do it justice, its a Big chunk of glass. I just Love this lens. Yours is in Great Shape! very clean!
Thanks! I'm looking for a wet plate lens that is a little faster than my 6.3.
