For Trade WTT Velostigmat 9-1/2 SF for 14-20" Fast Aperture Lens

I have a Wollensak Velostigmat 9.5 (branded as a Photex) with soft focus adjustment in a Optimo 4 shutter (slow speeds are slow) Lens is in fair condition, some light marks on the front and rear, a couple of tiny spots but nothing which is going to show up in your image.

I shoot wetplate on 8x10 and really need a longer portrait lens for that. Preferably 5.6 or faster, preferably 14" or longer.

A shutter would be nice but not critical as I doubt I'll be shooting any film with the rig.

Thanks for any help...
