thanks to both for valuable info.
I've just looked at TNA pix and Register entry for 238105 and neither the image, now attached, nor the 'comments' column in the Register, provide any clue as to what aspect of this design the Registration was protecting. But, in view of comments from Christine and Fred, and looking at the various decorative patterns within the other baskets then I'm sure they are correct in telling us it's the design of the handle only that was the subject of this Rd., and not the body of the basket.
You can see from the Kew image that the original Greener factory drawing for 238105 shows a 'hobnail' pattern plus Iznik/Persian sort of centre circle design, which is a match for the blue uranium basket shown by Christine.
However, it appears that by the time we get to Fred's 1888 rustic-handled basket, there was a name change leading to Greener & Co., plus what seems to have been a change of heart regarding their approach to Registrations. Whilst I accept that one identical pair of lozenge details on these twig handle pieces tells us it must be for the 'twig handles', I'm really unsure Fred as to what the other identical pair are protecting.
My thoughts are that it isn't the body pattern since both bodies have different patterns - is it more likely do you think that it might have been for the scalloped rim of the body, or possibly the shape of the body - both of which are the same on each basket??
Unfortunately, I don't presently have Kew Register details or pix for 1888 to help.
