well i purchased a cam off of ebay that was advertised as an afm n-41 cam. i got the cam in and it looks great, but it has n-412 engraved on it. i looked it up on their website and it looks to be pretty dang close to the n-41, but a change in some of the wording they used in its description lead me to believe it's a tad bit smaller of a cam than the n-41. the powerband seems to be a bit lower. anyone know the specs on it? i've looked everywhere and haven't found anything. here's what their website says about the N-41 and N-412:
