Model 41 brass muzzle brake

Anyone ever hear of a brass muzzle brake for a model 41? It looks like it would fit on the 41 but wouldn't really do much. It almost looks like some ones attempt to add weight. It is certainly interesting looking.

It looks like an unfinished muzzle break project with those odd holes in the side.  The fact that it's made of brass does suggest the desire to add weight.

I saw that one and just thought it was homemade
