Anyone familiar with Le Grelot model 42 razor

Trying to get some info on this model. Have only seen on the net two photos without any description. Size, grind, type, history... anyone?

Thanks!!!

Le Grelot 42 on this picture is 5/8 quarter hollow.

Thanks, Martin, the trademark history was interesting. The old TMs are very cool!
