Horseman Professional 105mm lens

Hi all--
I just ended up with a Horseman Professional 105mm lens/Seiko-SLV shutter mounted on a metal board (about 3"x3"). Anyway, I doubt I will every have that system to use it so I am thinking of selling it but I have no idea what they are worth. Anybody know much about these?
Thanks,
Matt

If the maximum aperture is f/3.5, it's almost certainly for the Horseman 980/985 cameras, so it won't cover 4x5. KEH has a 105 f/3.5 priced at $165 in EX condition, and a 105 f/4.5 at $235 in EX condition.
