For your consideration, here is a Bogen Sound Systems Catalog, no. 310-C, 11 pages. It has some wear on the covers and is a little curvy. There is a light stain on the front cover. There were a couple of pages that were stuck together and a small spot of printing is messed up. Lot of interesting information. Item pictured is the actual item for sale and comes from a non-smoking household. (44.930y-.7hc)
