Nice job Stevenski! Beautiful work. Glad to hear Alex is doing well, and glad to see you updating!
Ah, so that's where the distributer is on the 2CV- was wondering about that.
The horizontal cylander in the center of the frame is the starter motor, with the solenoid molded to it. The more vertical cylander in front of it as best as I can tell is an oil reservoir- this is where the oil fill seems to be.
And the alternator is the bump beside it on the fan housing.
Looking forward to seeing you do the engine!
