It would be made from scratch, not from cutting a mesh/grill, it's a much more complex shape than it looks, Sam would have spent a LOT of time creating a 3d cad of it to make his Splam grills originally. I'd buy the one for sale today to send to a company to copy it if viable.

Huh? What mesh?Getting hold of the correct type of mesh seems to be the problem. I can get them made ok if the mesh can be found.
It really doesn't need to be a 3D CAD. Buy an original, take it apart, lay it out in the most compact area, put dimensions into a 2D CAD program. Get quotes.
