I have had the first two rounds in my collection for over 40 years but have never managed to identify them. The last I have just acquired. The shrapnell shell case is 46.4 x 123R the base fuzed shell case is 37.5 X126R. Both of these two are heavily copper plated and neither case has any headstamps., just a pressed in primer. The lone shell is I believe Russian 47mm but the fuze thread is the same as No. 241 @ 16T.P.I. Could this have been modified . (when spun in the the lathe the fuze has a slight wobble or run out.)
