Glen â€” I had completely forgotten the 2616 asymmetrical sticky-out bits, or ASOBs. I have had 2616 vases both with the ASOBs and without, but I have never seen a 2616 bowl without its ASOBs. I don't think we have yet established whether the ASOBs were an add-on or a take-away, and I don't believe the illustration in the Sowerby trade catalogues helps, as Sowerby probably did not bother to change the illustration.
I believe that they were cut into the mould for the vase after an initial period of production of ASOB-less versions, and the bowl was a later production, always with ASOBs, but I could be wrong. I have also often wondered whether the Jobling 2-handled Rose Pattern Vase, No. 11200, Rd July 21, 1934, provided the inspiration.
Leni â€” Yours is neither a standard variation, nor a different reference number. Sowerby reference numbers are supremely logical. They started with 1 back in 18??, and added one for every new design they produced, right until they closed. Had you asked me last week if they had produced a square version I would have said it was unlikely. The moulding is too thick and it would be extremely difficult to line up the former used accurately with the ASOBs. I would describe yours as an unusual and unexpected variant.
Tigerchips â€” 11cm? If that is 4Â¼", then the plinth with that fitting would be Sowerby pattern number 2562.
Grateful thanks for changing your images to links, but you should not have just for me. If you want me to see an in-line image on my elderly home PC, re-size it to roughly 200x150 pixels, and optimise the file size to less than 32K bytes, although you will find that images this size, photographed against a plain background, will usually optimise to less than half that with no noticeable loss of quality. It is most unusual to need an image larger than this for id purposes. ... and you can cram much more into your valuable web space. Great-glass reference library images are optimised to less than 3K bytes, and they are still short of web space. I think Frank's are as well optimised but with more detail, so they have a slightly larger file size than the great-glass images, necessary for the subtleties of Monart and Vasart surface colour effects, &c.
