Anyone know meaning of these primer markings??

Picked this up yesterday from a charity shop for a pound. Just loved the markings.
any ideas??

No 15 Mk II N (Naval)
C in the pentagon - M Cockburn & Co., Falkirk. (manufacturer)
KBY - ROF Kirby - Filling factory
The BH and XU more than likely examiners' marks.

Thanks Tim for that.

Any chance anyone knows what case it went into?

I may be wrong, but it looks similar to my 2pdr Naval.

I have the No15 Mk11 in 6Pr 7cwt. Also noted in 6Pr 6 Cwt and 6Pr 10Cwt.
The ones in the 6Pr 7Cwt do not have an N stamped on them. They are too large for the 2pr cases.

You are correct. No. 16 is on my 2pdr Naval.
