Soprano Prestige 450 Series

[mramoni]

Apologies for the arcane question but is there anybody able to solve this mystery?

It is my understanding that Professional (or Model) 2000 IM Grassi were labeled by a 440 (S/A/T etc) series number while Prestige where labeled as series 460 (S/A/T etc).

Does anybody know what is a series 450? Is it a Prestige?

Thank you for your help.

Do you have pictures of it? It's becoming increasingly apparent that without pictures, it's impossible to tell some of the later models apart. I've seen Professional 2000s with silver keys, gold keys, different thumb rests, with or without the high F#, and a soprano that was COMPLETELY different than any other I've seen.

The only one that is always distinct is the "Wonderful" model and some of the Prestige 2000s, but there are variants of those too.

Thank you for the swift reply. Alas I don't, the horn is not mine yet. I just got a description. My question was about the meaning of this "parallel" labeling system (440, 450, 460) that seem to be related to the series (Prestige, Professional, etc).

Thank you again for your help.
