About a year ago, i purchased this voor trouwe dienst medal (model 1851)


And when i check the medal thoroughly i found these on the side of the medal

A strip and a "c" alphabet. So my question for the members of this forum is, is this strip and "c" alphabet is the maker stamp? Is there anyone know the history about the maker of this beautiful medal? I still searched for the answer of this problem and i hope someone can help me in here.

Thank you in advance
