* Change {90 to 80} Part White 3854 Window 1 x 2 x 3 Pane
Comments from Submitter:
In 2002 LEGO Education catalog it lists inventory as having 260 parts, saying "Possible to make 70 windows and 30 doors." Inventory appears to include 10 too many of the white windowpanes - even if included as extras, it seems unlikely that they would've added 10 extras. Jrspears, unfortunately, did not give a source for the inventory.
