Phonoland.com has a pretty good forum. Just click on the link on the right that says Forum... They have various sections dealing with a wider range of the phonograph hobby than we do here. I generally stick with the Acoustic Phonograph and 78's & Cylinders sections.

It sounds like an Edison Phonograph cabinet w/o the inner workings just by your description. There were several machines that were housed in the taller cabinets but w/o a picture or the model # it is hard to give a value. The ID plates with model designation were found either on the inside rear panel or on the left side toward the front.
