Add PCC 4260749 to part 42001 under Reddish Gold/Copper? Source: instructions.
The instruction booklet for this set provides many missing PCCs, but it seems
this set had many alternates, so it makes sense that many of these aren’t on
Bricklink.
Though I’m not quite sure if 4260749 is the PCC for the ‘Copper’ variant, it
might be worth adding anyway. This set does appear to have alternate parts according
to Bricklink’s inventory, one of which is the teapot, which appears to have made
a Bright Pink to Pearl Gold transition (Bright Pink Teapot’s PCC is also in the
booklet, but not on Bricklink). Sets around this time are known to have different
colors in different release waves, so it’s possible that the Bright Pink teapot
appeared in an early release with the ‘Copper’ crown.
