I have had a good look at my images of Arculus, Walsh Walsh, Richardson, and unknown Old English paperweights, and don't see any canes that resemble these. However, I do have a paperweight that has canes in the outer ring very like the green one in the close-up image, and with canes of the same style as the ones with the solid white centres (see below - open the link and you can compare the images side by side on screen).
Curiously, that was made by Whitefriars (signed / dated / labelled)....so whoever made Lothar's paperweight, I think there may well be Whitefriars canes in it. Of course, the presence of Whitefriars canes in a paperweight does not mean that Whitefriars made it - I have 3 paperweights with Whitefriars canes, but made by others.
