There's a note somewhere about using correct pricing of current items even when there's a mistake on the chronicle sheet. Probably lost to the Forum vortex though.
This is my opinion of how it works:
It is not within your GM rights to change the chronicle sheet.
However the players may only buy the bracers at the correct price, even though the chronicle sheet is wrong. If you wanted to make their life easier by noting that the price is wrong that might be helpful, but be very careful to be sure you're 100% right before doing this sort of thing.
