Picture 2 Dutch import and duty mark (Gothic E), no guarantee for precious metal, silver, gold...
Picture 4 Capital I. Also a duty mark for unguaranteed standard for gold and silver. Likely 13 loth as you assume, but?
In other words, your tray is imported "silver" and if so likely below legal standard and made abroad probably between 1906-1953
Strong statement without proof and without citing your source, merely your amateur opinion. You write below legal standard, which legal standard are we talking about?
Correction picture 2, not a Dutch import and duty mark but a Belgian import and duty mark, the Belgian Gothic E for Étranger = foreign, used
1832-1869
Correction picture 4, the script- capital letter I used 1906-1953; Dutch duty mark
for unguaranteed standard of fineness new silver objects of national origin. This mark was used on all new Netherlands silver objects below legal standard of fineness, those with non-precious metal additions, and new heavily silver plated objects, as long as the average precious metal content after melting with the base metal was at least 250/1000. It was also struck on rejected objects which had been submitted at lowest legal standard of fineness. In that case the maker had to choose between destruction or unguaranteed marking. This mark was sometimes mistakenly used on old and foreign objects and in 1927 also used on objects of old national origin. Valid from 1906 till 1953.

The marks 13 struck partly twice or 13,3 Lot?, 2nd mark capital letter A with serifs
If minimum 13 Lot = 812/1000, it is below the 2nd (lowest) Dutch minimum standard of 833/1000, as indicated by the Dutch duty mark the script-capital letter I
This silver tray, I believe to be German, with perhaps pseudo marks?
