Descriptions about the pianos of old versions.

I recently downloaded the old instruments that used to be available in older versions of Pianoteq. However, they do not have descriptions, there is no comment or text on the site talking about the characteristics, applicability or origin of these models (pianos). I just want to know a little more about these pianos.

I am not referring to those small descriptions of each preset, but to the broad descriptions presented on the site, such as Steinway D4, K2, Gotrian.

Can anyone give me some of these descriptions, or tell me how do I get them?

Thanks, friends of the forum. It is a great pleasure to have your support!
