Info on unusual Pinfire revolver

I would appreciate any info anyone can give me on this unusual pinfire revolver. It has no markings that can I see. It has an off set front sight.

Without any other information it will be very difficult and mayby impossible to say more about his revolver .

seems to be something between an Eyraud and a Michallon
