Polish Sugar Bowl - Julia Keilowa design???

[Tokkoloshe]

I acquired this a few days ago. The hallmarks seem to be for Poland, Lodz around the 1930's which ties in with the previous owners' claims that her mother brought it with her from Poland before WW2. It weighs 275g and is around 15cm in diameter. It is missing it's finial and has several dents (previous owner threw it at her mother).
It seems that not much Polish interwar silver has survived. Is this piece perhaps designed by Julia Keilowa? An online article by Culture.pl states that she did make items such as this from silver. They also show pictures of the 'Royal Apple' sugar bowl which has similar design characteristics. Further research also indicates that diagrams or sketches of her designs still exist. Obviously, if a picture of this piece exists, it'll help in getting a new finial made. Unfortunately, most articles are in Polish so my research options are limited.
Any suggestions...?
Thanks

Hi,

You are far more likely to get a response if you embed your images as few people will click on links.

Trev.

Here are a few different pics...

[Qrt.S]

The first mark from the left is a Polish warrant mark punched beside the primary assaying mark on articles of mixed metals. It was used 1921-1963 The second mark is the Polish assaying mark 1920-1963 indicating silver in the fineness of 800/1000. The capital letter L indicates the city of Lódz.

The problem is that the last marks, the left oriented bird, seems very similar to Aron Lewek Oksenberg's trade mark, but it cannot be him because he used this mark 1850-1893 and that is in contradiction with the other marks, so???? Let's wait if somebody else comes up with a better solution.
