Thank you for viewing. I am selling this item because I don't have time to build it. A and B are just separated into two parts; there is no difference. This is an unassembled and unopened item. It is Fine Molds 1/350 25mm Triple Machine Gun (2 boxes). Since it is unopened, I have not checked the contents. Please note that we cannot respond to initial defects due to the number of years since purchase. Shipping is planned via Yu-Pack. Please note that we cannot be held responsible for accidents during transportation or initial defects. Please check the photos carefully. Please be aware that the outer box shows signs of aging commensurate with the number of years since purchase. Please refrain from purchasing if you have reservations about personal storage or are concerned about the storage condition. Please understand that we cannot accept claims, returns, or price reductions. #Fujimi #FineMolds #HeavyCruiser #JapaneseNavy #ShipModel #Warship #Ship #PlasticModel #Model #MachineGun #1/350 #Crew
