This Dummy, or Drill round, is of all brass construction, with a ‘plug hole’ approximately half way down the case.
I could not find any reference in Fred A. Datig and I am informed that there is no reference in B.A Temple No4 (I or II).
It is know that the round was in circulation during WW2. However; it is not known if it predates WW2.
Any background information would be much appreciated.
