I think you're right on this one, I believe there was some variation among different production batches for some sets (another example is the astronaut helmet - 3842a or 3842b - of classic space minifigs). I'm not an expert on this subject though... Up to now I've used the rebrickable parts lists as a reference, since I understood it is quite reliable (any advice or opinion someone?)
