The base 310 was used in a few Calatravas with narrow bezels. The only difference afaik between the 310 and 335 are the hour wheel, minute bridge, date wheel, and the 335 has two riser plates on the dial side.
On Dandong’s infamous SL-4530, nearly all parts (including balance complete) are interchangeable with real Rolex 4130 parts. That isn’t the case for their 324 clones, maybe the date wheel and rotor are interchangeable but that’s probably it. It does follow the same basic design as the 324 though and is roughly the same size. Counterfeiters do sometimes add their own free-sprung balances, which is interesting but I doubt they keep good time. Whether intentional or not, I think the very visible LIGA etched third wheel on the 26-330 will be a very effective anti-counterfeiting measure.
The sterile versions (used by Atelier Wen) assembled in the Dandong / Peacock factory and are presumably good movements. I wouldn’t touch the ones in replicas with a ten foot pool, they might not even be oiled 😬.
