I have for sale a US Army Signal Corps TG-5-B Telegraph Set. Has a J-41-A key attached. In good shape however the door to the battery compartment on the rear is frozen shut due to rust on the hinge. Included is the set itself with the original earphone and canvas case. I had a printout of the instruction manual which I will include if I can find it. $75 shipped, PayPal preferred. Please contact via my email on qrz. Thanks!
