@Seigetu1941 I think of it as slab sided. Also it makes me think of Lady Rachel MacRobert who donated enough money to buy one after her three sons were killed flying for the RAF.
@KrypTanko No problem! Not sure where the other photo came from though, maybe a film still? I also think the book says it wrong in the description paragraph, that's the T45 they're referring to just calling it the T95.
