Lost Scottie dog...please help

This little fella fetched up at the boot sale. It has simply got B.I.F written in brown on the base. It feels very early '30s to me; the glaze feels like Clarice's Latona; the colours are quite Cliffy/Shortery/Crown Devony (notice the theme?). However I can find no other Scottie dogs webside that look any thing like it. Any thoughts, oh oracles of ceramicastan?
B.I.F might mean it was made for a British Industries Fair perhaps......

Just adding Price bros/Price Kensington, Empire Ware, Clews, Beswick, Sylvac,
Wade Heath, maybe more.

Does anybody recognise this particular dog? I've googled scottie dog book ends and loads come up but none looks exactly like this.

Might be a Sealyham

But modern pedigree dogs look different from their ancestors of 50 or so years ago due to kennel club rules on what they consider to be breeds best attributes.
