Thought these might be of interest, though not cup dischargers. The one in the poorest condition is also the rarest. I have never seen one before exactly the same. It is fabricated from two separate pieces of steel riveted together. I was led to believe by a Frenchcollector that it is an early example of the 'launcher' for the No23 Mk1, 2, & 3 grenades. The chap who found it lives in Bernafay Wood on the Somme, & he found it in the wood, which his family own.
