I believe that the A D on either side of the crossed halberds is for a 1998 reproof date if the pattern follows prior practice - 1997 was Z C on either side of the crossed halberds so A D would be the logical follow on.


i know the nitro proof and date codes

but my question was Birmingham or London marks?
