Grosse Tierce French

While this name is most often used as a synonym for Tenth, Douglass provides an alternate definition:

Some builders used [the name Grosse Tierce] for the Tierce 1-3/5', in order to differentiate it from the narrow scale seventeenth, as occasionally found in organs earlier in the century (Petite Tierce).

Examples

No examples are known of a Grosse Tierce at 1-3/5' pitch. Contributions welcome.
