Hi,
At least one more mark is needed.

Scratch test on stone is not reliable at all. False positive result from silver plated layer.
Only deep filing where it cannot be seen, then polish.

Hi,
Hanau pseudomarks; I think an example of trade mark crossover. The ram`s head in the middle was used by Brothers Dingeldein.
Crowned letters A and P were used by several makers.

Hi,
Regno Lombardo Veneto until 1872 (the mark in the middle - the globe with stars).
To the right; the mark looks like town mark for Verona.

Hi,
I think it is older German orthography with Ö and TH in the end of the word LÖTH .Danish and Norwegian alphabet have letter Ø, Swedish has letter Ö, equivalent to German Ö, but 12 Loth was not used. In short, I think it`s German.

Most likely the pin is hollow (impossible to mark).Therefore,the mark is commonly seen on C clasp, even on the needle itself.

Hi,
The form of the marks looks like Austria marks used after 1922 (imported in 1925; letter k, right ?)

I think it is 13 loth (.813 solid silver).

Hi,
Looks like Austria-Hungary Empire; the style and the engraving are typical for second half 19th century.
Imperial warrant eagle, maker`s mark and town mark (possibly a lion); several candidates.

The back of the marks is completely wrong; what are those strange counter marks, irregular impressions, pitting - arrow 1? They are really not supposed to be here. Even if the clock was repaired and removed from the frame, there are issues when it was put back (there was no need for excessive filing...

Engine turned guilloché was widely used by British silversmiths in XVIII century.

Hi, From left to right: A stands for second quality plating (the first, highest quality, i.e. grams of pure silver used for electroplating was A1). The crown was discontinued on silver-plate some time in late 19th century because of confusion with Sheffield Assay Office sterling mark. The maker is D...

Hi,
Cannot be French if there is only one mark. Looks like lacquer,rather than enamel, just guessing / Japan.

What about Pisa, Pescara, Perugia, Pordenone,Pistoia, Prato ?
No makers with 33 or assay offices were abolished ?

The notstempel-frei, freistempel nFRs on your items is for big articles (Tardy).
It is controversial to have both Repunzierung and freistempel FR on the same piece.
Can you read the engraving on the chalice ?

Hi,
This is perfectly genuine form; many Russian crosses made of gold and silver look like this one; almost typical.

The province should have two letters, but here only the first letter is seen; there are too many provinces codes starting with P, meaning it`s impossible to identify the maker unless you decipher the ...
