looking for a lens for my speed graphic, petzval or aero ektar
Jim Galli has a petzval for sale, complete with sample photos from a Graphic here on APUG:

Pretty different beasts. You'll probably need both.
I have an unused Aero Ektar I would be willing to sell for the right price or trade.
f/22 and be there.
