I’m in the process of restoring this A277 but some chrono parts need replacing and possibly are missing. Anyone know where I can find the tech sheet for cal 146HP? Unfortunately Zenith was unable/unwilling to provide it.

It appears we’re possibly missing the following three highlighted components. Would appreciate if someone can provide the part names/numbers of the red, blue, and green highlighted parts:
