While much of what you have is antiquated stuff (the Elwood enlarger and the studio camera), it's worth something to the right buyer. The lens on the camera alone could be worth a few hundred dollars to the right person, depending on make, model and condition. A good place to read up on such equipment is the large format forum, http://www.largeformatphotography.info/forum/ A good many of the folks who post here belong there as well. You can find information on old cameras and lenses from catalogs posted at http://www.cameraeccentric.com/info.html The catalogs will at least give you an idea of the year and type of lens.
