For sale is an exceptional U.S. Army Signal Corps Telegraph Set TG-5-B, a rare and highly sought-after piece of WWII communication history. Manufactured in 1944 (as indicated by the data plate marking “CAKU ORDER NO. 9753-PHILA-44”), this set is in “like new” condition, making it one of the finest examples available on the market today. Complete with its original CS-49-A canvas carrying case, J-38 telegraph key, and PROTEK-SORB desiccant bag, this TG-5-B is a museum-quality piece perfect for serious collectors, historians, or reenactors.

The TG-5-B was a critical tool for the U.S. Army Signal Corps during World War II, enabling secure, point-to-point communication via Morse code in the field. Used when radio silence was necessary or in environments where radio signals could be intercepted, this portable telegraph set played a vital role in tactical operations. The device is housed in its original olive drab canvas case (marked “CS-49-A”), featuring leather-reinforced corners and a sturdy shoulder strap for easy transport. The case shows minimal wear, with crisp stitching and no significant damage, reflecting its careful storage over the decades.

Inside, the TG-5-B is pristine, with all components intact and fully functional. The set includes:

• A J-38 telegraph key with brass components, perfect for sending Morse code.
• A sounder for receiving messages, complete with an “ADJUST” knob (labeled “BK-7-B”) to fine-tune sensitivity.
• Binding posts (L1, L2, TM1, TM2) for connecting telegraph lines and grounding.
• Original internal wiring, neatly bundled, with a circuit diagram on the lid providing setup instructions.
• A PROTEK-SORB desiccant bag (4 oz, manufactured by The Davison Chemical Corp.), included to prevent moisture damage during storage—an uncommon accessory that adds to the set’s originality.

The metal case bears the data plate reading: “SIGNAL CORPS TELEGRAPH SET TG-5-B, SER. NO. 1470, CAKU ORDER NO. 9753-PHILA-44,” confirming its wartime production. The interior components show no signs of corrosion or significant wear, and the set appears to have been meticulously maintained since its manufacture. This TG-5-B is not only a functional piece of history but also a stunning display item, capturing the ingenuity of WWII-era military communications.

Whether you’re a collector of Signal Corps equipment, a WWII history enthusiast, or a curator looking for a centerpiece for your display, this TG-5-B is a rare opportunity to own a near-mint example of a pivotal wartime tool. Don’t miss your chance to add this extraordinary piece to your collection.
