Oops! My apologies - I forgot, it's a RAF aircraft !
It wouldn't have the K-14 sight, or the N-9. It would be fitted with the sight the K-14 was derived from, the British GSGS MkII, in service from late 1943. Basically, the K-14 looks almost identical, but the 'crash-pad' on the front of the British sight was rectangular, rather than curved.
I'm afraid I'm not familiar with the 'beacon' you mention - can you provide a bit more info, or a pic?
