Right on Plynkes! I think you will find there will be bench seats added for this version.
There are bench seats on the version depicted on this topic! I can see them, they just happen to be in the folded up position.
So I guess the other version would have them in the 'down' position. An alternative would I suppose have been to simply have them as separate pieces, and you glue them up or down as you prefer. Though I guess that would make the model more complicated. I for one like wargaming vehicles to be simple, leave kits with masses of pieces to the "proper" vehicle modellers.
