Is this a Australian MK 3 Igniter? I have BB as an Australian company.

Found loads of these in the UK, BB seems to ring a bell on marking.

I have BB as Bertram Bullet Co. Australia.
Is there a British BB manufacturer?

It is not Bertram Bullets. They only made brass cartridge cases. I doubt it is Australian.
I would guess Bluemels Bros, UK who made bike parts etc but no proof for ID.
