I wonder whether anyone is able to help with the identification of an engraved monogram on a group of replica forest glass vessels and a vase in the style of Whitefriars. They come from two unrelated British collections but all four pieces have the same engraved monogram on the underside - looks like it could be LTO or something similar (almost certainly L and T, the third letter could be O, C, U or perhaps not a letter at all. Two have been in the same collection since before 1998 so they will have been made over 25 years ago. I understand there were (and still are) a number of makers producing replicas like this. The obvious suspects would be Mark Taylor & David Hill (who usually sign with a full name and date), Graydon Stannus (who usually marked 'Gray Stan'), or possibly Whitefriars as they have similarities to some Powell pieces. There was a suggestion that they may be Tiffany as the initials resemble LCT - but I don't think they are. Perhaps someone here recognises the mark?
