Hi folks,
Just wanted to alert you all to an error in the printed plans of
5140 - Rotrock-Kanonensegler. It shows the part composed of four light brown sail spars as 30 51 7740, but that part number is already in use: it's the
rollbars in
4863 - Beach Buggy. I'm confident that the previous use is correct since other 30 51 77* parts are from the same year - that's almost universal, that numbers within a group defined by the third and fourth digits (in this case, the "51" group) are used in chronological order. "51" parts from 2011 are up in the 9000 range.
In short: this part, shown on the plans of 5140, has the wrong number. The plans with the error are
30 82 8312 - Instructions for 5140.

I've left it out of the inventory for now. If anyone sees reprinted plans for this set with a different number for this part, please let me know!
