There is no SAP for 6Pr 7Cwt of WWII era, only AP, APCBC and APDS and of course nose fuzed HE, so I believe 2 Pounder is probably right.
It does not appear in my book. It is 1955. I should probably have had a look round in the forum. Thanks tankbarrell.
Oops! I forgot about this lot, there is the very SAP.
None of these are mine.
The number on the base may refer to the fuze and looks very ww2 to me, Bonnex might have an idea.
If this is made for ww2 use with HE the fuze would not be the same as for the older Black powder filled
types. Is that a C around the Broad Arrow ?
