This paperweight was made by Caithness Glass, Scotland. It was made in 1995, designed by William Manson which explains the WM cane alongside the flower. Yours is evidently number 14 of a proposed limited edition of 150, but in the end, 132 were actually made.
So, what help do you want? Value?? Well, as has been said many times before on these pages, you have not hit the jackpot. Caithness paperweights do not currently fetch even what was paid for them when made. And check if the side or top facets have any nicks on their edges. These weights need to be damage free. Hope this helps. Steve
