Probably worth trying Cavellito's for a reproduction.
Someone in Italy must be making them, they are cut from solid, not cast,
Last time we were in the Biscarreti De Ruffia Museum in Turin in 2006 they had them for sale, unfortunately the Biscarreti is shut for reorganisation, but a friend brought one back for my 2c in about 2002, and I'm pretty sure he got it from Cavellito.
