British Coal Flag

[ncb1973]

I've managed to aquire a British Coal flag that is about 8ft x 6ft & looks almost in new condition.
What I would like to ask is, were they up all the time at collieries? or were they just put up for special occasions?

Don't know about the British Coal Flag, but with the advent of Nationalisation in 1947, it was often the custom to fly the flag when the target tonnage for the week had been reached.
