this is something from Sunday morning, and because of the partly worn mark which can be seen in one of the pics, prompted me to look thru my few books to try and decipher what came after 'E &....'. - there didn't seem to be much re Edinburgh Crystal. So getting nowhere, I started to type the post, but then eureka found all the Edinburgh Crystal marks in a very useful little softback called 'British Glass betwen the wars'. So now I know, and the book tells me this was their first acid mark introduced c. 1927 and on into the early 30's. I admit my ego also wants to show the piece - a stunningly beautiful cut vase, probably about 1930, with this striking pale straw lemon colour, and whilst there is some wear on the base the rest of the piece is unmarked. The answer to the missing part of the mark is.. "E & L" - referring to the Edinburgh and Leith Flint Glass Works. I wud genuinely recommend this book, especially if you collect pre 1950's British glass, it is a very interesting and useful read. Paul S.
