You can even cast brass at home if you are sufficiently adventurous, I

Brass is a pig to cast. Bronze is _so_ much easier.

This wouldn't be an easy shape to cast, as you have to flow into those
deep, thin sides. Not a hard bit of patternmaking, but I'd use
Petrobond sand (by the kg from mutr.co.uk) and a traditional open
mould, not my usual lost foam.

Apart from lost wax, the "lost frog" process is amusing...
