Help with identifying Moscow maker's marks

[Atlas]

So, help would be appreciated with identifying the following Moscow maker's marks on the picture down below regarding the small (width 17cm) bowl in these pictures if you please.

Best regards,
-Atlas-
P.s. I apologise the somewhat poor quality of the photos. I can try to take some better ones and post those here a bit later on.

A slightly better photo, at least partly. Moscow hallmark is clear in this one.

If the stamps are genuine, then I think they are around 1840.
I can't remember the name of a suitable silversmith starting with the letter "A" right away, but I'll try.

[Atlas]

The assay-master is Dutkin, active in Moscow 1838-1846.

The initials "НД" belong to the head of the assay institution Nikolai Dubrovin. I am interested in the initials of the silversmith.

[Atlas]

Ok. Thank you for your answer.
The maker's marks is my main interest also.

Interesting case, but could be him because Dubrovin's full name was НИКОЛАЙ ЛУКИЧ ДУБРОВИН. However, if Dubrovin punched НЛ, who punched НД in Moscow 1826. I have a photo of such a mark.

[Qrt.S]

According to Postnikova #2104 Dubrovin's punch was НЛ but according to Ivanov it was НД (ref. Green Ivanov p. 609)So what is correct?
