Thanks Mike - that's around the same that replicas are here now, about £12 to £15. As mentioned, only three or four years ago, you could buy a plain Iron Cross replica for anywhere between 50p and £1, in any of those arty crafty shops which sell everything from joss sticks to Chinese jingly things. It's the sort of thing bikers or wannabe 'Hippies' would wear on a chain around their necks. Now, they can't be found, except at those places supplying replica outfits for re-enactors - hence the huge rise in price.
I only considered one as 'dressing' on the base of a model display, so might make one out of Milliput and card, then cast it, maybe in resin or plaster, get a bit of ribbon from a haberdashery, and job's a good'un !!
