Bestwood Colliery(New Hucknall) Pre 1947 Pit Check.

A Pre 1947 Brass, Embossed Bestwood Colliery Pit Check. This has been overstamped with New Hucknall, this was another Notts Colliery. I think what's happened here is that Blank Bestwood Colliery Checks have been Reused at the New Hucknall Colliery ?, the Regular, New Hucknall Pit Checks are of the same shape with their numbers stamped on the Reverse. This makes it a Unique Bestwood Colliery Check Varient. I'd be interested to know, if someone has an Alternative Theory?.
Good Condition.
