I believe this is Favre’s contribution to the Extra Precision family, this example ca. 1920-21.

This appears to be the higher-end precursor to the 151, which was necked down to 5.25L and has an evolved setting mechanism. They share a common setting spring, likely other parts.

My two caveats:
1) I'm wrong many times a day --just ask my wife!
2) Always seeking to learn more
