Identity required please!

For a friend, anybody tell me what it is? A Webley .45 perhaps?, I am out of my comfort zone with these things, cartridges (shot shells) are my love.

The K would make me say Kynoch and the II, mark 2 cant make my mind up what the other letter is apart from a G maybe?

Sizes are.
O/A = 1.235"
Case = 0.765"
Case Dia = 0.476"
Projectile = 0.442"
Head Dia = 0.532"

Many thanks,

C for cordite load.
