Actually, Liskeard (with a k, not a g) can be found in Ivo's book. It is included in the list of makers of 20th century Paperweights - under the "Paperweights" heading. It is really my own fault that it is not listed in the main headings. I did some review work for Ivo on a few things but I never properly completed my task :oops: so a comment that Liskeard was 'missing' never got passed on.
In John Simmonds book, Paperweights From Great Britain 1930-2000, there is a brief mention of Liskeard in the section for "Other Makers and Studio Artists". He states that in the 1960s the company used Murano canes and in 1976 they made abstract design weights. Apparently, all the weights had the impressed logo on the base - but in the book the logo shown is "ST", for St Tudy, a Cornish village.
I don't know how the 1960s / St Tudy info ties in with Liskeard Studio Glass being stated as 1978 - 1983 . And in the earlier link to the paperweight, the item is shown with an embossed "LG 1977" which seems to pre-date the 1978 start of Liskeard Glass ... :?
But Liskeard is 13 miles from St Tudy, which itself is only 7 miles from "Merlin's Cave" (tourist attraction) which may be the source of the current name of the company "Merlin Glass".
