If that is for a whole rotor, that is a steal for sure, and as long as it really is new, I would snap that up. If that is just for the rotor pinion, that not @ terrible price on the open market, so still probably a good buy.

It’s just for the rotor pivot, part 550 1429. There doesn’t appear to be much availability on the open market at the moment

Always great to see somebody succeed at their first vintage omega purchase. Congrats! That’s a nice one.

Sounds good - just remember that once the new pinion is installed, it has to be reamed to size in order to fit the rotor axle.

Ah yes, I saw a post of yours that said there are two straight reamers provided by Omega for this purpose and if I remember correctly, the tolerance is so fine that the larger one is only one micron larger in diameter!
