HP-15C 25th anniversary edition

An impression of this only, as I have only learned the history by reading posts and other web information.
The original 15C was in production from 1982 to 1989.
In 2011 for a short period a new 15C Limited Edition was released. The hardware was based on the current iteration of the HP-12C, with new software and printing.

The 12C Platinum model does have a 25th Anniversary edition released in 2006, is it possible you have that one?
