awaiting arrival of a velostigmat WF 20" process and hoping it will have good coverage as a taking lens on 8 x 10 plus couldnt find info on a 20 WF in the old catalogs

Dave, I don't have an answer for you but this link may help. You may have already seen it...

It is a copy of a Wollensak process lens catalog.

Hope it helps,

thanks John,
the chart shows 19 inch and 25 inch with the 19 covering 14 x 17 full plate, but i am supposing that means at 1:1 since this is a process lens?

Dave, I got one some time ago and can't recall if it says it's a Velostigmat or not. But I wrote about it (there was a url link here which no longer exists). Shine a pin lamp into that bad boy when you get it. If you see 2 brights and 3 dims per group, it's the protar type. I know they changed to dialyts fairly early on though. If it is the protar type it'll cover that bad old 14X17 with movements. And have very nice contrast to boot.

Thank you jimbo and I will do the test and publish the findings
