SHOWCASE 8. CELL 8-11

T17a (Ln 26999) - Luftwaffe straight key, part of FuG 17 airborne radio set. Because FuG 17 keying was in plate voltage circuit, T17a had a pair of safety contacts installed which would disable the circuit when key lid was open. Made by Graetz. Our T17a sample was seriously damaged before arriving in our collection.
