Victorian Silver Hair Work Mourning pendant

Nice Silver Hair Work Mourning pendant with the Antique Dutch Sword hallmark for 1814 - 1906. You can see it on photo 3. The other mark (photo 4) probably the maker I cannot decode. Who can help to find the maker?
I've read in the data of the past about mourning jewelry, these were often created by family or friends of the deceased. The reason was that professionals used not the hair from the deceased given by the family but in practice they used frequently the wrong color of hair, so someone else's hair was used. Therefore often relatives were advised to make there own creation for their mourning jewel. So a lot of women made them at home with a book as guide. Therefore there exists books about this subject or they attended special classes to learn to do this kind of handicraft home. .
This kind of jewelry could be set in pendants, earrings, brooches etc. . The brooch I showed you earlier on CW.
