Set of Spoons from Hamburg with different makers, maker “H.W.F.K.”

[Joerg]

I got this set of spoons from Hamburg, 3 dessert spoons, and 7 coffee spoons. The have the same monogram, are identical in the design but are from different makers. To comply with the forum rules I post each maker separately. Can you help me identify the maker and an approximate manufacturing date? Also, some spoons have a sub-supplier identification number, can you help me with them too?
Thank you, Jörg

Here maker “H.W.F.K”?, the letter of the town mark is C, sub-supplier identification number 29

I do not understand the "ConzessionsNo"

there is the 29 and makersmark of
Heinrich Wilhelm Friedrich Krumstroh

I now the same No29 with makersmark [AN] = ohann Friedrich August Noack

and I have the makesmark from Heinrich Wilhelm Friedrich Krumstroh
with the No 39

Using the input from Theo I found an old post ferom 2009 from Theo and Blackstone.
There they state:
Heinrich Friedrich Krumstroh (1813-1876), Master 1842

Assay master "C" is again Friedrich Christoph Greve (1829-1854)

So this spoon dates between 1842 and 1854
