The British 4in series of guns has many different case lengths but most carry the Mark of gun they belong to. Pictured is what I think is a case from the start of the the line, the QF Mk I, II and III. The case is 368mm long with a rim of 137mm and is clearly separate loading. The primer adapter is probably original, as it is stuck fast! I think it is electrically initiated. I thought to include a couple of pictures against the 4.7in MkI to IV case, and big brother 6in MkI to III case.
