Something wrong?

[amena]

I found a tray with these marks.

It should be Egyptian before 1946, but I can't find the date letter on the lists.
Is there anything wrong?
Thanks for attention.

Hi Amena,

Here's another example of the mark:



I'm unsure also.

Assay office Cairo above fineness mark ٩٠ = 90% silver, Egypt Country Mark- Silver = Cat, used 1916-1946. Date Hallmark جـ used July 1945 till May 1946.
Nothing wrong the 2nd silver hallmark with the core image of the standing Egyptian temple cat, here facing left and tail raised was changed in October 1946 to the Nymphaea lotus flower blossom.

Thanks Peter for the confirmation. On the internet I found lists with date letters other than this on my tray. On the other hand, I was sure it was silver (tested with acid). As usual, however, I was unable to confirm the purity from the density test.
I have detected a weight in air of 901 g and a weight in water of 810 g, which leads to a specific gravity of about 9.9. Evidently air bubbles or anything else make this test absolutely useless.
Best regards
Amena
