this cut and etched marmalade is Reg. 288500, and differs from the other marmalade No. 288499 in body shape and pattern of cutting and etching - and these differences are substantial enough to avoid any confusion.
Both designs show vertical cutting around the base plus mechanical etching in the upper half of the body........ oddly enough - as you'll see in due course - the original factory drawings, for both, show a hooped handle, and not a central finial on the EPNS lid as appears in the photo from Chris.
I have Kew pix for all three of these Seago, Johnson Registrations - 288498/99/500 from 16.01.1875 - the butter and two marmalades, but need to re-photograph both marmalades for better close up size, so will show 288498 only for now.
Of the other five Registrations mentioned in my earlier post No. 6 ...................
280660 is an ink well as stated, and will be included in the 'Ink Wells' thread in the coming days.
297633 is a design for a cruet of some description, and I also need to visit Kew for this item.
303996 is a butter, and I've included this one here too.
309484/85 are another two I need from Kew, so will be a few days yet before I can post.
Just as a suggestion, might it be of any benefit to include this Registrants name in the subject heading ?? - might not make any difference of course............... it does get confusing with some of these pressed glass threads when they become heavily visited and acquire a lot more information, and pictures etc., than just the Registration No. they started out with.
