on which aircraft is this Indicator installed?
 

Gentlemen, maybe you can help me to find out on which aircraft the following described Flight Director Indicator (ADI) as part of the Collins FD-108 system is installed:

Details:
Manufacturer: Rockwell Collins
Type: 329B-7
P/N 522-3122-012

On this indicator the LOC-indication is replaced by a "FAST-SLOW"-indicator and the GS-indication is replaced by the "RADALT"-indication.

I have not seen this type of indication before in comparison to the "usual" LOC- & GS-indications.

Boeing 727?
