Right, Rockhopper, have just checked and see that you are an overnighter on Friday.  So, nab me in Bologna and I shall give you details of the 2nd hand shop at Colney Heath, near Hatfield, that specialises in exactly the kind of stuff you're looking for.   Depending on your travel arrangements, I could point you in their direction on Saturday afternoon, even lead you there if you wish,  and you can browse the 2nd hand bits of cr@p ... sorry, desirable fireplace artefacts, to your hearts content .... and take them back to your neck of the woods. 
  Don't say I never do anything for you
