Philosopher… Even with that weight parity throughout the set, sir, my hunch is that you have an original Raschig Bumblebee matched with non Raschig colours. I’ve seen that quite a lot.
It’s impossible to be sure purely judging by a photograph, of course, but those colours and lustre don’t look like Raschigs to my eye and the black bubble box pushes me further in that direction.
Boogieman. You can buy what is described as an Aramith Nine Ball Set from Ortmann Billiards which looks just like the Raschig Turniersatz. Beware though, dear chap, I purchased one myself out of curiosity and the quality was dreadful.
Note that the image shows numbered balls, sir, but once on the order page it is possible to tick a box for a numberless version.
