Help! I bought my dad a 1970's MIB B-29 Superfortress from an online seller last night as a gift but on reviewing the photos this morning it has a leaflet for the B-17 Flying Fortress in one of the images. (I have contacted the seller to ask about it but it's already been dispatched) I don't know anything about planes but I want to make sure I'm giving him the correct plane when it arrives so what are some (super obvious) things I can check to make sure the plane in the box is definitely the B-29 Superfortress? Thanks!
