This is a Dublin import mark. I cannot work out from your picture what the date letter is, but it is from the cycle 1916-1941. The sponsors / importers mark is unknown to me; I read it as RB&Co.

Many thanks for your help I can now confirm its date as 1925

I have to say that I would not have read that letter as a “k”.
