Quote:75174p01c01 call the part 30130, but the official part is probably 6133;No, this is exact, 6133 is opaque while 30130 is transparent. Because the material is different, mould (thus its number) is different too.
Quote:43123 call the part 40344, but the official part is probably 32531.Same transparent/opaque difference, but indeed, 43123 is opaque, so it should call 32531 (40344 is transparent)
Things are muddier for magnet, looks like 4106 and 2959 are aliases.
