I have a little bit of equipment left after selling most of my gear off a few years ago. I'd like to sell it, but have no idea where to find a rough idea of what it's worth. What I'm looking to sell is a Horseman L view camera with the telescoping rail. It's the basic L model, not the one with the base tilts. I also have a Schneider Symmar S 5.6 210mm, a Schneider Symmar 150 mm, a Sekonic Digi-Pro X1 flash/ambient light meter, two Prontor shutters (a #1 and a #0) along with the Prontor remote control. Everything is in very good to excellent condition. Any ideas as to how to find out what this stuff is worth would be much appreciated.
