I had a quick look and unfortunately couldn't match the bell and letter M, and laurel leaf mark. Also, I might just add, it would help when researching marks, to see the front of the pin as it often provides important historical information concerning the success of a hallmark determination.
The other mark, we can just see, could be the clincher. It could be a country mark.
I can research further but will need clear photos close-up shots of the marks, another image of the entire piece and another image of the marks and the surrounding area.
