Small jug from Berlin?

[cathycat]

Hello,

may I please ask again for your help.
I have a small collection of jugs, this is the first of them.
13,5 cm high and 15 cm wide , with handle.

What I found out so far, or at least what I think I found out...:
After turning this a couple of times round I think the hallmark on the right shows a bear with a little K on the side.
Could be from Berlin, the K stands for C.S. Kessner (1819-1854).

Similar item which I found on the internet showed a letter A on the left, the period of B.G.F. Andreack 1819-1842.
Here on my jug there is a B on the left hand side.
Which period might that be?

And the silversmith is called Reifs or Reiß?

Any help would be very much appreciated.
Thank you.

Yes Reiß is correct

Joseph Ferdinand Reiß *1800 in Bernsdorff
oo 5.5.1827
retired? 7.8.1854

Thank you, @ Theoderich !
First question solved, great !

Do you have any clue about the letter B ? Which period or person it stands for?

Brilliant!! :)

B = Ch. F. Deppe, 1842 — 1847

That matches the others dates perfectly.
Thank you so much for your help. :)

If I am allowed to, I will be back with the second jug soon..
This will be even more difficult, three tiny hallmarks, hardly to recognize and I don't have the slightest idea about age and provenience.
