agree the details on the glass aren't too clear, but my opinion is that this is more likely to be 626977 for Greener which is dated 22/10/1913 - I'd suggest this as much as anything else because the 'Blue Book' omits reference to Rd. 686977 (would be early in 1922 I think). This later No. might be for a glass item, but equally could be for wood, metal, ceramic, or a wallpaper design.
Unfortunately, I can't help with any National Archive images for these two Nos. - apart from a few that I've photographed especially, I don't automatically have pictures after early 1884, but can of course include these two when I next visit, in the coming days.
Fred might possibly have more to say on these Registrations. Some sort of comport perhaps - but probably an unlidded sugar - they didn't seem to have a problem with obesity in those days, and consumed sugar at a rate of knots.
P.S. I've tried to view the link from tigerchips, which I assume is the previous reference to Rd. 626977 referred to, but it seems to lead nowhere
