This Collins 32S-1 Trasmitter Original Manual 520 5796 00 8th Edition 15 Feb. 1960, is in fair condition. The Cover binding has been repaired with tape and the schematic diagram also has some tape on the back side to re enforce the creases. I will provide a Plactic sleeve to protect the cover and binding.Why buy a copy when you can own an original for about the same cost?
