I am impressed with the dedication & diligence of the "Team" Vio.
Interesting: 基本No.3セット (Basic No.3 Set) could be G-26, G-27 (unconfirmed) and G-28. We don't know why it could have these numbers for now.
D-51きゅうこうれっしゃ (D-51 Express), G-19
家畜車 (Livestock Car), MS-28
Keeping an eye out for MS-29 and G-18, because these numbers are unconfirmed at the moment.
Interesting, very different box for sure and thats looks to be the dual AA battery in Tender train you have spoke of too.
Wow, look at all those. This fellow must have a masterful collection. Does he have Plarails from all era's?
