Hi Eric, According to Dr Sturgess, who has written the definitive book on the subject, the commercial Luger cleaning rod was of "one-piece non-demountable pattern with a blued steel grease drum handle, with a permanently fixed (hard-soldered) one-piece shaft/jag, made of brass". He goes on to say that the shaft was of 5.5mm diameter, and 179mm long (for 120mm barreled pistols). The final 55-58mm was turned with a coarse thread, 12 turns to the inch (Whitworth).
Regards, Norm
