Vintage boning/filleting knife identification

[Ruari]

I saw this boning or filleting knife in a recent bundle sale. The pic isn't too great, but it looks like a Remington 'R' on the face of the blade, with what looks like either a '54' or '84' stamp or mark.
Judging by the length of known knives in the bundle, I would say this is an 8" or 9" blade.
Any help with ID of the knife (maker, year etc) would be greatly appreciated.

Looks like a Remington tyle R to me.
Do you know what it says on the snap.

Hmmm, no idea what this says! Almost looks like the word/s start with a 'B'

OK, some newer, better pics of the boning knife.
It's not a Remington 'R', but an 'IR' and the figure '84'.
The snap on the sheath says 'Belconia'.
