I show three Projectiles for the Armstrong BL Gun. I think this is the correct ID.
6Pr 2.5" Solid shot. 64.5mm Diam. 135mm Long. Marked H ^ . RL on base.
12Pr 3" Common shell? 77.5mm Diam. 172mm Long. Marked R^L L 4/64.
12Pr 3" Common shell Mk11? 210mm Long. Marked RL^LA 11/68 11.
The Mk 11 is in two sections. Why is it longer? What fuzes are used with these projectiles?
The Mk1 has a left hand thread. The Mk11 has a rirht hand thread.
