Really nice finish on such a tiny kit.
Interesting note: Apparently Airfix molded the driver's cab wrong, in the Mk1 the driver's cab should hit the edge of the tracks, they only narrowed it to have a gap between the cab and the track for Mk. II and onwards in order to mount wider tracks. Takom also did this on their Mk. I tank in 1/35 scale which annoys the heck out of me because it's way more noticeable in that scale.
