Dear All, What was the name of the mine where the UKAEA utilised the adit (Excelsior), for a trigger test. I know I have the vol. with p.graphs. of the mine entrance at the test date(and the history of the mine - inc. a p.graph of the cottage where Captain 'somebody' (a military Capt. who owned and lived there during the final part of the mines working life). I think this could well be an NMRS vol.(?), but can't find it yet as I have forgotten which vol. it's in!!! It's very irritating, I know I have seen it, and I know I have it... but I can't find it! Regards, Bernard
