Cool. I know that you and I were discussing this in a different thread. Also notice the radial lines from the bell outward on the top pics. Unless the bell was heavily lathed, you may even feel the ripples on the topside of the bell, kind of like on that vintage splash that I had. Not necessarily drip, like on the Bionic or Natural rides, but definitely some markings in metal that appear to be moving out towards the edge of the pie.The plot thickens.
I think this might be the kind of look you are describing. A pyramid stamp UFiP 20" which doesn't have much obvious hammering, but is covered in those metal "runs" which look like they were formed in the mold as the metal was cooling. In some of the 3 photos you might think they were lathe chatter but they certainly don't look like that in person.

And on a very different looking (older?) 20" UFiP we have much hammering visible, but still that telltale on the bell.

The bell on this one (I've got two of them actually) is very steep sided and totally unlike the gradual one of the shiny 20".

The steep sided bell with thick bell to bow transition is something I'd only expect to be able to get on an Italian cast cymbal. Starting from a flat blank it would be very hard to do without leaving the transition area too thin. And for Turkish style cymbals where a press is used to put the bell in, they just don't have straight sides. Maybe a few Chinas have bells with sides this abrupt, but I don't have any to examine them closely.
