Only FWs I ever had problems with are Helicomatics, and the single Regina CX I own(bought close yo NOS)....
Helicomatics eating their puny bearings and the Regina CX having internal pawl area clearance problems (never mind it's seeming propensity to seize on to hubs.) That cause horrible knocking sounds when freewheeling...... Had to actually open it up and use the Dremel on the FW body to fix it.
Not sure if I'll readily consider buying Reginas again......unless it's an America Superleggera, for a good price, maybe.....
In contrast, all my much cruder looking Maillard and Spidel (Non-Helicomatics) FWs, lots of them bought used, never gave me any problems through the years.....
