I have tried a variety of 'replacement' sources, and came up with without a match. In view of the fact that you have confirmed this one is E&L - probably sometime around the '30's, then the pattern may well have been sufficiently long since abandoned to be unavailable from anywhere now. Although that is my guess only, and for all I know Edinburgh Crystal may have in fact continued this one for a very long time (although proabably not since we can't find it). Some patterns like Woodchester and Stratford for example (Stuart) seemed to have been produced for ever. It's a long shot, but much leg work trawling around antiques fairs/markets may well be your only hope (and a slim one at that)
P.S. throw it away and buy 1/2 doz. of another more recent pattern.
