Thanks gents, great information and thoughts, I knew it was a long shot when I bought it. There were a couple of colliery's in the area with their own Home Guard units, but I cannot find any evidence that the Maypole colliery had one, so I agree that this is a "cobbled" together group but for £20 there is no loss involved and I need a Defence medal for the ARP ephemera that I have just picked!
