A google search yields few results for lutetian glass, mostly ended ebay auctions.
This
one is similar, altho the colors are off (google buffered page).
I have saved some images with lables from previous eBay listsing but can't post them due to copyright.
The Lutetian Glass paperweights usually have a frit flowerpot, I thought the flowerpot in the picture looked like Ardalt canes
but the picture isn't clear enough to be sure - the colors appear similar to the usual Ardalt colors.
I have found very little on the makers of these (the Japanese) weights online.
A caveat tho - this flower arrangement is a fairly common theme in paperweights, as I mentioned earlier I see it frequently in Swedish
paperweights, usually at tradera.se, a Swedish subsidiary of eBay.
It is quite possible that a British maker made similar weights
