LF Enlarging lenses

A friend of mine has some enlarging lenses for sale, and he's asked my advice on pricing. If anyone out there can help, I'd appreciate it. Also, if there's any interest in any of these lenses, please let me know.
Thanks,
Steven

360mm f 6.8 Rodenstock Rodagon-G
300mm f 5.6 Rodenstock Apo-Rodagon
135mm f 5.6 Schneider Componan
135mm f 5.6 Rodenstock Rodagon (qty 4)

I'm not sure what it's worth, but I'd be interested in the 300mm
