Please help me identify the master?
I understand that this is the Russian Empire, Riga, 1908-1917, and what is this round mark?

[Mart]

"НВ", Hermann Bank.

Interesting. Would you mind explain a bit more. To my understanding Hermann Bank's punch was HBANK RIGA. He also used a HB mark.
He was born in Königsberg 31.5.1857, became master 20.1.1895 and died 1927. When was this mark used??? Moreover, are you sure it is HB and not something else like HK? Riga it is but the mark?
...Just asking...

I had to write the word “presumably” because I haven’t studied much about the hallmarks of Baltic silversmiths. However, if you look in the same book at the version of the Erich Bank mark, you can see the similarities.
Silversmiths could have many variants of their hallmarks.

@Mart
Even more interesting

"...presumably...."? What you wrote was only :

"НВ", Hermann Bank.

A rather absolute statement.

Yes, masters could have used several different punches for several reasons.
Anyway, I cannot find anything indicating that this conjoined mark (HB or HK mark) would have any connection to Hermann Bank. Of course it is possible, but how to verify it? As I already mentioned Bank used also a not conjoined HB mark.
Mind my asking but what "same book" are you referring to? Unfortunately this Erich Bank is unfamiliar to me. In addition, his mark would most likely have been EB hardly HB, or? Kindly tell me more about him, thank you.

Last but not least. I wouldn't draw hasty conclusions on deficient information. I still consider the shown mark to belong to an unknown master. But yes, it could be Hermann Bank but with reservations.

The crest on the stem belongs most likely to Berens von Rautenfeld in Latvia.

Thank you very much for the information about the coat of arms!

These are just the features of the translation: “I had to write...”. It's clear what I meant. That I should have used the word "perhaps" in my first post.

Nice doing Mart, but you could have showed this source in the first place, thank you. The maker is now pretty obviously Hermann Bank like you mentioned earlier. The mark must be Hermann's newest/latest mark. Unfortunately I don't have Leistikow available for the moment. This case is verified to all parts even the crest is identified.

Thank you for your help!
