Want to Buy Long 8x10 Glass - 600mm+

I've been shooting a lot of 8x10 wet plate but my longest lens is a 300mm which really isn't cutting it for a lot of landscape stuff where I'd prefer to get in tighter. I'm on a complete paupers budget since I'm spending six months traveling around the country working on a photo book but if someone has a long bit of glass they're interested in lending, selling or possibly trading for other gear please get in touch. I'd like at least 600mm. Aperture doesn't matter.

Thanks!

I wouldn't have had to step in cow shit to get this shot if I had a longer lens

PM sent regarding 760mm Rodenstock APO f14 lens.

Consider the Wollaston Meniscus lenses made by Reinhold of APUG. They are very cheap and gives very nice images.

He recently posted here about a 1000mm f.13,7, but theres an array of other lenses, and as far as i know these are <100$ shipping included. He also mounts on boards and has different shutters he can provide.

Found a 21inch f/10 Eastman Anastigmat that should do nicely.
