The letter "K" in the item number means "King Size" or about 1:48 scale which works well with Lionel O gauge size. The regular size is 1:64 scale (a little smaller). Grading the condition is a little different than the train grading system. The vehicles are graded as follows: MODELS:

MINT - as made, virtually perfect

NEAR MINT - a small imperfection or two but showing no playwear

EXCELLENT - a toy with some minor playwear that still has a new appearance at arm's length

VERY GOOD - a toy with obvious wear, but still presents well

GOOD - a toy that is 100% intact but shows fairly extensive playwear; may be missing some original parts or show signs of fatigue

FAIR - a toy with very extensive wear and missing a good portion of the original paint. Parts may be missing and fatigue evident but the model will have a somewhat complete appearance. With the exception of rare models, pieces in this condition are not collectible. BOXES:

MINT - as made, virtually perfect

NEAR MINT - sharp and bright with a Mint appearance with a couple of slight imperfections

EXCELLENT - a box that may either show some loss of brightness, an area of minor graffiti or an area of fatigue but still presents well

VERY GOOD - a box that will show a combination of fatigue, graffiti, staining or fading of color, but is structurally sound with a decent overall look

GOOD - a box with extensive wear and fatigue which may be evidencing some paper loss, but still is displayable.

FAIR - a box with damage bad tears, missing an end panel, complete sides obscured by graffiti - minimally collectible and displays
